Answer: 841 / pi inches^2
Step-by-step explanation:
circumference of circle on the sphere = 2*pi*r
surface area of sphere = 4 * pi * r^2
29 inches = 2 * pi * r
r = 29 / (2 * pi) inches
surface area of sphere = 4 * pi * r^2
= (2 * pi * r) * 2 * r
= (29 inches) * 2 * (29 / (2 * pi) inches)
= (29 inches) * (29 / (pi) inches)
= 841 / pi
exact answer is 841 / pi inches^2
which is approximately 267.7 inches^2
