What is the area of the shaded region?
(25π – 48) cm2
(25π – 30) cm2
(25π – 24) cm2
(25π – 12) cm2

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the circle minus the area of the two isosceles triangles

so

Find the area of the circle

The area of the circle is equal to

where r is the radius of the circle

In this problem we have

substitute

Find the area of the two triangles

The area of the two isosceles triangles is equal to

we have

substitute

Find the area of the shaded region

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

126 maybe. sorry
