2 The cone in number 2 above has a diameter of 8 cm and a height of 15
cm. What is its volume?
b) 125.6 cm b) 1,004,8 cm c) 320.00 cm d) 251 2​

Answer 1

1 . option b

2. option d

Explanation:

1) Diameter = 8cm

Radius = 8/2 = 4cm

2) Diameter = 8cm

Radius = 4cm

`Volume = (1)/(3) \pi r^2h = (1)/(3) \pi 4^2 * 15 = 16 \pi * 5 = 80 \pi = 251.2cm^3`
