the volume is 20 you have to add the inches i graphed it and the units were 20 so the volume of the cone 20

The formula for the volume of a cone is V = PI x r^2 x h/3

r = 1/2 the diameter. 1/2 of 8 = 4 inches.

h = height = 12 inches.

Using 3.14 for PI, the formula now becomes:

V = 3.14 x 4^2 x 12/3

V = 3.14 x 16 x 4

V = 200.96 cubic inches.


You do not say if the answer needs to be rounded, so round the answer as needed.

A circle with radius 3 has a sector with a central angle of 1/9 pi radians
Art [367]

The area of sector is 1.57 m²

<u>Explanation:</u>

Given:

Radius, r = 3 m

Central angle of a sector = 1/9π radians

Area of sector, A = ?

We know:

Area of sector, A = \frac{1}{2} r^2 \alpha

where,

α is the central angle in radians

On substituting the value we get:

A = \frac{1}{2} X(3)^2 X \frac{1}{9}X 3.14\\ \\A = 1.57 m^2

Therefore, the area of sector is 1.57 m²

Rewrite the following without an exponent<br> (-7)⁻²
chubhunter [2.5K]

Answer:

The correct answer is 1/49

Step-by-step explanation:

In order to find this, we first can eliminate the negative in the exponent by putting the whole this in the denominator.

(-7)^-2 = 1/(-7)^2

Now we can evaluate the denominator

1/(-7)^2 = 1/49
