Determine the area of a circle whose diameter is 8 a.) 50.24 square inches b) 50.24 inches c) 200.96 square inches d) 200.96 's the answer

We can find the area of any circle with the formula
Where r is the radius. We have the diameter but we need the radius.

Luckily, finding the radius is easy if you have the diameter because the radius of half of the diameter.

8 / 2 = 4

And we will let = 3.14

A = (3.14)(4)^2
A = (3.14)(16)
A = 50.24

So, the area of the square is A) 50.24 square inches.

The distance from point a to point c across the coordinate plane is aproxamatly 8.94 rounded to the nearest hundredth. you use a^2 + b^2 =c^2

The answer is the numbers between =5 and 5
