Question 5 of 10

Answer 1

Answer:

25$in^2$

Step-by-step explanation:

To find the area we need to use the expression $\frac{x}{360}$ · $\pi r^2$

When you substitute and solve you should get 25$in^2$

Answer 2

Answer:

25 in ^2

Step-by-step explanation:

First find the area of the circle

A = pi r^2

A = 3.14 ( 4.3)^2

A =58.0586

The take the fraction of the circle that is shaded

A circle is 360 degrees

155/360

155 /360 * the  total area = area shaded

31/72 * 58.0586 = 24.99745278 in ^2

Rounding yields 25 in ^2
