Question

The height of a cone is 15 cm. If its volume is 1570 cm3, find the radius of the base. (Use π =3.14)

Answer 1

Answer:

10 cm.

Step-by-step explanation:

We are asked to find the radius of the base of a cone. where the height of the cone is 15 cm. and the volume is 1570 cm³.

Now, the volume of a right circular cone is given by 1/3(πr²h), where r is the radius of the base of the cone and h is the height of the cone.

Hence, we can write 1/3(πr²h)= 1570

⇒3.14× r²×15/3 =1570 {Given that π =3.14}

⇒ r² = 100

⇒ r=10 cm. {Ignoring the -ve value as radius can not be -ve.} (Answer)
