Question

what is the surface area of a sphere with a volume of 140

Answer 1

Sa = 4pi r^2

V = (4pi/3) r^3

Answer 2

r = cbrt(3V/4pi) ..... maybe ☺

Answer 3

options are
880
130
420
339

Answer 4

130!

Answer 5

Volume of sphere is 4/3 *pi*r^3=140
Surface area of a sphere is 4*pi*r^2=3/pi*(4/3*pi*r^3)=3/pi*(140)

Answer 6

130 if i did it right

Answer 7

i got 133.69 blah blah
