Find the area of a circle with a circumference of 53.42 inches

226.9 in²

Step-by-step explanation:

The formula for circumference of a circle is:

C = 2πr, where π = 3.14 and r = the radius

The formula for area of a circle is

A = πr²

First, using the formula for circumference, you can solve for 'r':

53.42 = 2πr or 53.42 = 6.28r (divide) r = 8.5

Now, use the value of 'r' to solve for area:

A = π8.5² or 3.14(8.5)² = 226.9 in²

844

Step-by-step explanation:

First. we do 30 x 30, which we can make easier by doing 3 x 3 [9] and adding two zeros to the end. This gets you 900. Next, we add four [904.] And then subtract 60, which gives you the end result of 844.
