Question

Whats the volume of a cone? Lengths: 9cm, 5cm

A)225cm^3
B)75cm^3
C)25cm^3
D)15cm^3

Answer 1

B) 75π cm³

Explanation:

The volume of a cone is given by the formula ...

V = (1/3)πr²h

Your cone has r = 5 cm and h = 9 cm. Putting these values into the formula gives ...

V = (1/3)π(5 cm)²(9 cm) = 75π cm³
