Question

Which is closest to the volume of this circular cone?

A. 452.4 cm3

B. 603.2 cm3

C. 150.8 cm3

D. 1,809.6 cm3

Answer 1

C

Explanation:

The volume of a cone is:

(π)(r)^2(h/3)

The diameter is given as 8cm but we need the radius and the radius is half of the diameter meaning 4 cm.

And the height is 9cm

(3.14)(4)^2(9/3)

(3.14)(16)(3)

(3.14)(48)

150.72

Closest to C

Hope this helps :)

Answer 2

Explanation:

here's your solution

=> volume of circular cone = (1/3)πr^2h

=> radius = 4 cm ,, height = 9 cm

=> volume of cone = (1/3)*(22/7)*16*9

=> volume of circular cone = 150.8 cm^3
