Answer:
The perimeter of the rectangle is 93.4m
Step-by-step explanation:
F
irst of all we have to calculate the width, for this we will use the area formula of a rectangle
a = area = 159.1m²
l = length = 3.7m
w = width
a = l * w
w = a / l
we replace the known values
w = 159.1m² / 3.7m
w = 43m
Now we use the formula to calculate perimeter of a rectangle
p = perimeter
w = width = 43m
l = length = 3.7m
p = 2w + lw
p = 2 * 43m + 2 * 3,7m
p = 86m + 7.4m
p = 93.4m
The perimeter of the rectangle is 93.4m
Diameter=16mm, so the radius is 8. The formula for volume of a cylinder is the area of the base times height, or v=πr²h.
Substituting the values in, we get π(8²)(5.7), which gives us roughly 1146mm^3.
