Answer:
22 in
Step-by-step explanation:
<u>circumference of a circle = 2 π r</u>
where radius (r) = 7/2 in. = 3.5 in
C = 2 π (3.5)
= 22 in
We know that
[surface area of a sphere]=4*pi*r²
r²=surface area/(4*pi)
r=√[surface area/(4*pi)]
surface area=450 in²
r=√[450/(4*pi)]------> r=5.98 in------------> r=6 in
the answer is
r=6 in
