Question

Suppose a coffee cup has a diameter of 8cm and a height of 9cm. What is the volume of the cup ? (to the nearest whole number)
A) 81 cm^3
B) 226 cm^3
C) 452 cm^3
D) 1018 cm^3

Answer 1

Answer:

452 cm^3

Step-by-step explanation:

The volume of a cilinder is $\pi (radius^{2})(height)$

The diameter of the cup is 8cm, the formula of the radius is $\frac{diameter}{2}$

So the radius would be $\frac{8}{2}$ = 4cm

We change variables in the formula of the volume $\pi(4^{2})(9)$ = 144$\pi$ = 452cm^3
