The radius R of a sphere is 7.3m Calcualte the sphere's surface area A. use the value 3.14 for pie, and round your answer to the nearest tenth.

Question

anonymous · Answer

surface area = 4pr2
r=7.3m
surface area=669.32m^2

anonymous · Answer

$$surface area =4 \pi r^{2}$$ 
plug in the values given$$area =4 \times 3.14 \times 7.3^{2}$$
$$area=669.3224m^{2}$$
round to the nearest tenth
$$area =669.3 m^{2}$$
