Answer
B) 287.6cm²
Step-by-step explanation:
First you need the radius, since you have the diameter you have to divide it by 2 in order to get the radius (8.4 divided by 2 = 4.2) then use the formula A=2πrh and plug in the radius and your height (h) which is 10.9cm into the formula.
The length and width of the rectangle are 5 inches and 1 inches respectively.
<h3>How to find the length and width of a rectangle?</h3>
The length and width of the rectangle can be found as follows;
l = 3 + 2w
area of a rectangle = lw
where
Therefore,
5 = lw
5 = (3 + 2w)w
5 = 3w + 2w²
2w² + 3w - 5 = 0
Hence,
2w² + 3w - 5 = 0
Therefore,
w = 1 and w = - 5 / 2
width = 1 inches
length = 3 + 2(1) = 5 inches

For x=3
3 + 3·3 + 5 = 17 ≠ 33
For x=5
5 +3·5 + 5 = 25 ≠ 33
For x=7
7 + 3·7 + 5 = 33 . . . . . this is the solution
For x=9
9 + 3·9 + 5 = 41 ≠ 33
The answer would be 5.68*10^-3
