Answer:
251.33 = 251
Step-by-step explanation:
V= πr²h = π·2²·20 ≈ 251.32741 = 251.33
Perimeter of any figure is all its sides summed up
for a rectangle, with two equal pairs, that means, length + length + width + width or 2length + 2width, or 2(length + width)
but we know the length is 7/5 the width
width = w
perimeter = P
![\bf P=2\left(\frac{7}{5}w +w \right)\qquad P=240\implies 240=2\left(\frac{7}{5}w +w \right) \\\\\\ 120=\frac{7}{5}w +w\impliedby \textit{let's multiply both sides by 5} \\\\\\ 600=7w+5w\implies 600=12w\implies \cfrac{600}{12}=w](https://tex.z-dn.net/?f=%5Cbf%20P%3D2%5Cleft%28%5Cfrac%7B7%7D%7B5%7Dw%20%2Bw%20%5Cright%29%5Cqquad%20P%3D240%5Cimplies%20240%3D2%5Cleft%28%5Cfrac%7B7%7D%7B5%7Dw%20%2Bw%20%5Cright%29%0A%5C%5C%5C%5C%5C%5C%0A120%3D%5Cfrac%7B7%7D%7B5%7Dw%20%2Bw%5Cimpliedby%20%5Ctextit%7Blet%27s%20multiply%20both%20sides%20by%205%7D%0A%5C%5C%5C%5C%5C%5C%0A600%3D7w%2B5w%5Cimplies%20600%3D12w%5Cimplies%20%5Ccfrac%7B600%7D%7B12%7D%3Dw)
and the length is 7/5 of that
Answer:
B or C,i think. I'm not sure though
