Question

some on help me plllz
a sphere has a surface area of 32in^2
a,radius=_______ b,volume=_________

Answer 1

Surface area of a sphere = \(4\pi r^2\)
\(2=4\pi r^2\)
From this r(radius) can be found in terms of \(\pi\)
Volume of a sphere=\(\large\frac{4}{3}\pi r^3\)
Can u find nw? @this

Answer 2

sa=4pi r^2
32/4pi=4pir^2/4pi
32=r^2
i dont know what to do next):

Answer 3

32/4pi=4pi r^2/4pi
8/pi=r^2
to find r. find the sqrt of 8/pi
r=sqrt(8/pi)

Answer 4

to find the volume use
v=4/3pi r^3

Answer 5

thanks so much @ajprincess

Answer 6

Welcome:) Did u find the volume?

Answer 7

i got 2.25=r is that right?

Answer 8

pi=?

Answer 9

i cancel out the pi

Answer 10

what did use for pi? 3.14 or 22/7?

Answer 11

i use 3.48

Answer 12

wait let me show u how i did it the whole thing

Answer 13

ok:)
