Find the approximate area of the shaded region of the figure below.
A: 489.44 cm2
B: 181.72 cm2
C: 27.86 cm2
D: 49.07 cm2

D:49.07

Step-by-step explanation:

The area of a rectangle is LxW and the area of a semi circle is (πr^2)/2

Because you are finding the area of the pieces around the semicircle, you would subtract the area of the semicircle from the area of the rectangle:

(LxW)-(πr^2)/2

Length=14cm, Width=9cm

R is the radius of the semicircle which is half the length, r=7cm

(14x9)-((π7^2)/2= 49.07

10000

step-by-step explanation: divide by 2,

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
