Question

a cone has volume 3696 cm cube and height 12 cm find the area of its base ​

Answer 1

Answer:

∴ the area of base is 924$cm^{2}$

Step-by-step explanation:

volume of cone = $\frac{1}{3}$ $\pi$  $r^{2} h$

∴ 3696 =$\frac{1}{3}$× $\pi r^{2}$× 12

∴ 3696 =$\pi r^{2}$ × 4

∴ $\frac{3696}{4}$  = $\pi r^{2}$

∴ 924 = $\pi r^{2}$
