Question

Which is closest to the volume of this circular cone?

Answer 1

Answer:

C

Step-by-step 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

Step-by-step 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
