How are the radius and the diameter of a circle related? If needed, draw a picture on a piece of paper to help you explain.

Hello!

The radius is the distance from the center of a circle to the edge of a circle. The diameter is the distance across the center. The radius is always half of the diameter, as it is halfway across the circle.

I hope this helps!

What is the difference in area covered by a single 3 inch windshield wiper operating with a central angle of 138 degrees compare

Elena-2011 [213]

Answer:

38.9 square inches.

Step-by-step explanation:

We are asked to find the difference in area covered by a single 3 inch windshield wiper operating with a central angle of 138 degrees compared to a pair of 5 inch wipers operating together each having a central angle of 114 degrees.

We will use area of sector formula to solve our given problem as:

$\text{Area of sector}=\frac{\theta}{360}\times \pi r^2$ , where, r represents radius and theta represents central angle.
