Answer:
h = 21.5cm.
Step-by-step explanation:
<em>Step one:</em> Simplify the volume.
220.16 x (pi) = 691.65cm^3.
<em>Step two:</em> Isolate h.
Cylinder volume equation: V = (pi)(r^2)(h), where r is the radius and h is the height.
Divide out the pi and r^2 on both sides to isolate h and move the equation to V/(pi)(r^2) = h.
<em>Step three:</em> Solve for h.
691.65/(pi)(3.2^2) = 21.5cm rounded to the nearest tenths place.
To illustrate this, please check the diagram below.
Answer:
<em>3 3/4 feet</em>
Step-by-step explanation:
Given
Perimeter of the garden = 20ft
If he wants the length of the garden to be 2 1/2 longer than its width, then;
L = 2 1/2 + W
L is the length
W is the width
Perimeter of the garden = 2(L+W)
P20 = 2(5/2 + W+W)
20 = 5 + 2W+2W
20 - 5 = 4W
15 = 4W
W = 15/4
<em>W = 3 3/4 ft</em>
<em>Hence the width of the garden is 3 3/4 feet</em>
