Question

pls give me step by step explaination​

Answer 1

Answer : 220 cm²

Given :

The slant height of a right circular cone is 10 cm and its base radius is 7 cm

To find :

It's curved surface area

Solution :

Radius of the cone = 7 cm

Slant height of the cone = 10 cm

Curved surface area of right circular cone

= πrl

= 22/7 × 7 × 10

~ Seven gets reduced

= 22 × 10

= 220 cm²

Answer 2

Step-by-step explanation:

l=10 cm

r= 7cm

curved surface area = 22/7 X 7 X 10

= 22 X 10

= 220 sq cm
