Question

What is the approximate volume of Zadie's decoration, to the nearest cubic inch?

Answer 1

Correct Answer: B

Step-by-step explanation:

We need to find the volume of a cone. The formula to use is:

`V=(1)/(3)\pi r^2h`

Where

V is volume

r is radius

h is height

Given, diameter = 10.

Radius is half of diameter, so

r = 10/2 = 5 in

r = 5 in

Also, given height is 24

h = 24 in

Substituting into the formula, we get our answer:

`\begin{gathered} V=(1)/(3)\pi r^2h \\ V=(1)/(3)\pi(5)^2(24) \\ V=628.3 \end{gathered}`

The correct answer is B
