What is the area of a circle to the nearest foot of the circumference of the circle is 8 ft ?

16π ft²

Step-by-step explanation:

To calculate the area we require the radius.

Given circumference (C) = 8π , then

2πr = 8π ( divide both sides by 2π )

r = 4

Then area (A) is

A = πr² = π × 4² = 16π ft²

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36
