Question

Find the volume of a sphere with diameter 21 cm.

Answer 1

r= radius

Answer 2

this is what i did
volume = (4/3)*pi*r^3

d=2r

v=1/6 pi d^3

=1/6*pi*21^3

=4849.05cm^3

Answer 3

you have to use dived 21 by 2 first then plug it in for r

Answer 4

its
r*r*r *4/3 that is the aproximite awnser mltyply it by pi to get the exact awnser

Answer 5

@nicoleee23 does that help at all?

Answer 6

yea thanks
