Answer:
395.841
Step-by-step explanation:
2 \pi r^2 = 2 \pi(7\text{ m})^2\approx
2πr
2
=2π(7 m)
2
≈
\,\,307.87608\text{ m}^2
307.87608 m
2
Top and bottom circles
\underline{+\ bh = (2 \pi \ 7\text{ m})(2\text{ m})}\approx
+ bh=(2π 7 m)(2 m)
≈
\,\,\underline{87.964594\text{ m}^2}
87.964594 m
2
The side is a rectangle with base = circumference
\text{Add them up:}\phantom{=}
Add them up:=
\,\,395.840674\text{ m}^2
395.840674 m
2
Final answer
\approx
≈
\,\,395.841\text{ m}^2
395.841 m
