A- Since the radius is 22, the area is 1520.53, or, 1520.5 simplified.
The answer is 120 sections.
Here's an explanation:
The rope is 105 feet long, and each section needs to be 7/8 feet. So to find the number of sections, you need to divide 105 by 7/8. 105 divided by 7/8 gives you the quotient 120. So there are 120 sections.
The circumference of the circle that has a radius of 28 cm is: 175.9 cm..
<h3>What is the
Circumference of a Circle?</h3>
Circumference of a circle = 2 × π × r, where r = radius of the circle.
Given that a circle has:
radius (r) = 28 cm
Therefore:
Circumference of the circle = 2 × π × r
Plug in the value of r
Circumference = 2 × π × 28
= 175.9 cm.
