Question 2 Mensuration Exercise 17.3

Find the surface area of a sphere of radius : 10.5 cm



The curved surface area is equal to the whole area of the sphere since the sphere is completely curved in shape.

Given radius of the sphere, r = 10.5 cm

Surface area of the sphere = 4π r2

= 4×(22/7)×10.52

= 1386 cm3

Hence the surface area of the sphere is 1386 cm2. M L Aggarwal - Understanding ICSE Mathematics - Class 10 chapter Mensuration Question 2 Solution image
