Find the area of a circle with a circumference of 12.56 units

ElenaW [278]

Answer:

12.56 square units

Step-by-step explanation:

The formula for circumference is

C = 2πr

Our circumference is 12.56. Using 3.14 for π, we have

12.56 = 2(3.14)r

12.56 = 6.28r

Divide both sides by 6.28:

12.56/6.28 = 6.28r/6.28

2 = r

The area of a circle is given by the formula

A = πr²

Using 3.14 for π and our radius of 2, we have

A = 3.14(2²) = 3.14(4) = 12.56.

How many sides does a regular polygon have if its interior angles <br><br>A. 156<br>B. 162

Kruka [31]

I) 156 degrees
The exterior angle is 180-156
=24
The number of sides= $\frac{360}{24}$
The number of sides= 15 sides

ii) 162 degrees
The exterior angle= 180-162
=18
The number of sides= $\frac{360}{18}$
= 20 sides
