Answer:
formula = pi× r²× 1/4
Step-by-step explanation:
since radius = 8
3.14×8×8 = 3.14×16
4
therefore the answer is pi × 16
16
area of a circle is pi x r x r
since it is a quarter
1/4 x pi x 8 x 8 = 16 x pi

Hello
The sphere volume is:
(4/3)*Pi*r^3
then
36 = (4/3)*Pi*r^3
36/[(4/3)*Pi] = r^3
8,5 = r^3
r = 3
