Question 1 Mensuration Exercise 17.3

Find the surface area of a sphere of radius : 14 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 = 14 cm

Surface area of the sphere = 4π r2

= 4×(22/7)×142

= 4×22×14×2

= 2464 cm3

Hence the surface area of the sphere is 2464 cm2. M L Aggarwal - Understanding ICSE Mathematics - Class 10 chapter Mensuration Question 1 Solution image
