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.

Answer:
-4y - 7x^3 + 2
Step-by-step explanation:
So first lets combine the y terms together, doing this we get:
-4y + 1 - x^3 - 3x^3 + 1 - 3x^3
Now lets combine the terms with x^3 together
-4y + 1 - 7x^3 + 1
Lastly, lets add the constants
-4y - 7x^3 + 2
