Question

if the volume of a right circular cone of height 9cm is 48 pie cmsq. find the diameter of its base​

Answer 1

Answer:

What is the formula?.......

Answer 2

Answer:

8 cm

Step-by-step explanation:

Volume of right circular cylinder = πr2h

48π cm^3 = 1/3 πr2h

48 cm^3 = 1/3 r2h

48 cm^3 = r2 1/3 × 9 cm

48/3 cm^2 = r2

16 cm^2 = r2

r = √(16cm^2)

r = 4 cm

thus,

diameter = 2r

= 2 × 4 cm

= 8 cm
