Question

What is the surface area of a tennis ball with a diameter of 6.7?? With full work please.

Answer 1

So the formula you have to do is A= (pie)(radius)(squared)


divide 6.7 by 2 to find the radius which is 3.35


now do 3.35 * 3.35 ( we are squaring it) which = 11.225

now 11.225 times PIE is 35.264377537


so the answer is 35.264377537

hope that helped!
