Answer:

[tex]r = 5[/tex] --- Radius

[tex]h = 3.9[/tex] --- Height

Step-by-step explanation:

Given

Shape: Cone

[tex]Volume = 97in^3[/tex]

Required

Determine different possible values of radius and height

The volume (V) of a cone is calculated as:

[tex]V = \frac{1}{3}\pi r^2h[/tex]

Substitute 97 for V

[tex]97 = \frac{1}{3}\pi r^2h[/tex]

Multiply both sides by 3

[tex]3 * 97 = \frac{1}{3}\pi r^2h*3[/tex]

[tex]291 = \pi r^2h[/tex]

Take [tex]\pi[/tex] as 3.14

[tex]291 = 3.14* r^2h[/tex]

Divide both sides by 3.14

[tex]\frac{291}{3.14} = \frac{3.14* r^2h}{3.14}[/tex]

[tex]\frac{291}{3.14} = r^2h[/tex]

[tex]92.68 = r^2h[/tex]

From the question, we understand that:

[tex]r \ne h[/tex]

So, we have to assume a value for either r or h and then solve for the other variable.

Let [tex]r = 5[/tex]

So, We have:

[tex]96.28 = 5^2 * h[/tex]

[tex]96.28 = 25 * h[/tex]

Make h the subject

[tex]h = \frac{96.28}{25}[/tex]

[tex]h = 3.8512[/tex]

[tex]h = 3.9[/tex] --- approximated

Note that there are other different possible values of h that is true for

[tex]92.68 = r^2h[/tex] where [tex]r \ne h[/tex]

Answer:

31 tests.

Step-by-step explanation:

The rate for the grading is 10.5 every 30 minutes.

Two 45 minute prep periods are 90 minutes.

90 / 30 = 3.

Since three 30 minute periods fit into 90 minutes, we get

3 x 10.5 = 31.5 tests.

Since a teacher did not finish grading the .5 of the test, we don't count it.

Our answer is 31 tests.

Step-by-step explanation:

y=x+5

Step-by-step explanation:

The opposite of y is x axis

Diameter of the circle in the middle = 8 ft

Radius of the circle in the middle :

[tex] =\tt \: \frac{Diameter }{2} [/tex]

[tex] =\tt \frac{8}{2} [/tex]

[tex] =\tt 4 \: ft[/tex]

Thus, the radius of the circle in the middle = 4 ft

Area of the entire circle :

[tex] =\tt \pi {r}^{2} [/tex]

[tex] = \tt3.14 \times 4 + 6 \times 4 + 6[/tex]

[tex] = \tt3.14 \times 10 \times 10[/tex]

[tex] =\tt 3.14 \times 100[/tex]

[tex]\color{plum} = \tt314 \: ft[/tex]

Thus, the area of the entire circle = 314 ft

Area of the circle in the middle :

[tex] =\tt \pi {r}^{2} [/tex]

[tex] =\tt 3.14 \times 4 \times 4[/tex]

[tex] = \tt3.14 \times 16[/tex]

[tex]\color{plum} =\tt 50.24 \: ft[/tex]

Thus, the area of the circle in the middle = 50.24 ft

Area of the shaded portion :

= Total area of the figure - Area of the circle in middle

[tex] =\tt 314 - 50.24[/tex]

[tex]\color{plum} =\tt 263.76 \: ft[/tex]

▪︎Therefore, the area of the shaded portion = 263.76 ft

Answer:

16 years approx

Step-by-step explanation:

Given data

P=$3000

r= 6%

A= $7700

t= ??

The compound interest formula is

A= P(1+r)^t

Calculate time, solve for t

t = ln(A/P) / r

substitute

t= ln(7700/3000)/0.06

t= ln(2.566)/0.06

t= 0.942/0.06

t= 15.7

The time is 16 years approx

Answer:

16.

Step-by-step explanation:

What does 75% Off mean? It means 75% of the price is subtracted. So find 75% of 64.

Here is our equation: 75/100 x 64 = 48.

So 48 dollars is going to be subtracted from 64, which gives us 64-48=16.

So the price of the wedding cake during the sale is 16.

Answer: Reflexive

Step-by-step explanation:

The property that illustrated by the following statement is D.  Symmetric

The reflexive property of congruence says that the considered geometric quantity, whether it be angle, line segment, or shape etc, is congruent to itself.

The symmetric property of congruence says, for objects A and B,

 if A ≅ B, then B ≅ A.

The symmetric property of congruence makes the  statement true:

 if ΔHXA ≅ ΔRGI, then ΔRGI ≅ ΔHXA

Here properties:

 Reflexive -- an object is congruent to itself: ΔHXA ≅ ΔHXA

 Commutative , the operations allow the order of their operands to be reversed: A +B = B +A for addition; AB = BA (for scalar multiplication)

 Transitive -- if A ≅ B and B ≅ C, then A ≅ C.
