Question

the radius of the base of cone is 21 cm and the height is 20 cm find the volume of cone

Answer 1

Answer:

8800cm³

Step-by-step explanation:

Given, radius =20 cm and height =21 cm

(by using $\pi$=$\frac{22}{7}$)

⇒Volume of a cone = $\frac{1}{3}$×$\pi$r²h

                             =$\frac{1}{3}$×$\frac{22}{7}$×20×20×21cm³

                             =8800cm³
