Answer:
593.04 square inches leather is needed.
Step-by-step explanation:
Leather needed to sew a ball = Surface area of the ball
Surface area of the sphere = 4πr²
= 4π(6.55)²
= 539.13 inches²
Since 10% extra material is needed for the seams, amount of material required = 539.13 + (10% of 539.13)
= 593.043
= 593.04 square inches
593.04 square inches of leather will be needed.
