The area is about 62.4 inch square
The are of a square is determined by squaring the side. And the length will hence, be determined by square rooting the area.
∴ length of this square is = √84 = 9.165
By definition, the volume of a sphere is given by:
V = (4/3) * (pi) * (r ^ 3)
where,
r: radius of the sphere.
Substituting we have:
V = (4/3) * (pi) * ((3) ^ 3) = 113.08 in ^ 3
answer
the best estimate for the volume of air in the balloon in cubic inches is
C. 113.1
