Question

what happens to the surface area of a sphere as its sides double?

Answer 1

LLAMAZ

Answer 2

Let's look at the formulas for volume and surface area. Plug one into the other and wherever you see area, just put in 2*area and that will tell you.

Answer 3

loll say radius ...its radius will change

Answer 4

how much find that out by following what kainui said

Answer 5

So I would plug in the area formula into the volume formula and vise versa?

Answer 6

surface area= 4pi(r1)^2
new after doubling
=4*pi*(r2)^2

Answer 7

but new area = 2*old area
4*pi*(r2)^2=2*4*Pi*(r)^2
r2)^2=2*(r1)^2
r2=(2*r1^2)^1/2
r2=(sqrt2)*r1
that is the new radius
