Answer:
r ≈ 2.39 inches.
Step-by-step explanation:
I think your question is missed of key information of the height, allow me to add in and hope it will fit the original one.
<em>The cylinder shown has a lateral surface area of about 750 square inches. Which answer is closest to the measure of the cylinder's radius? Use 3.14 to approximate pi. the height being 50 inches.</em>
My answer:
Given that the lateral surface area of about 750 square inches and its height is 50 inches.
We have the formula ti find the surface area of the cylinder is:
S = h(2πr)
<=> 750 = 50*2*3.14*r
<=> r ≈ 2.39 inches.
Hope it will find you well.
Answer:
Step-by-step explanation:
Rectangle:
Ratio = 3:2
Let length = 3x
Width = 2x
Perimeter = 55 cm
2*(length + width) = 55
2*(3x +2x) = 55
2*5x = 55
10x = 55
x = 55/10
x = 5.5cm
Length = 3x = 3*5.5 = 16.5 cm
Width = 2x = 2*5.5 = 11.0 = 11 cm
