Answer:
SA =64 pi units ^2
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
SA = 4 * pi * 4^2
SA =64 pi
SA =200.96

The constant is called the coefficient of proportionality or proportionality constant.</span>
Step-by-step explanation:
If radius = 6ft and height = 10 ft
volume of cone= (1/3)*pi*r^2*h
= (1*22*6*6*10)/3*7
(1*22*2*6*10)/7
3960/7
565.714
570ft
