Question

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.

Answer 1

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

Answer 2

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

Answer 3

what would the answer be if rounded to the nearest tenth

Answer 4

tenth is the the first place after the decimal point
