Surface area of one spherical ball = 4πR²
= 4 × π × (21/2 cm)²
= 1386 cm²
Leather required to make 5 such balls = 5 × 1386 cm²
= 6930 cm²
6930 cm² of leather is required to make 5 balls.

the area of sphere =4πr×r
=4×π×10.5×10.5
5 balls =5×4×π×10.5×10.5
=6927.2118
=4×π×10.5×10.5
5 balls =5×4×π×10.5×10.5
=6927.2118
