What is the area of the shaded region in the given circle in terms of pi and in simplest form.
a. (270pi +54radical3) m^2
b. (216 pi +54radical3) m^2
c. (216 pi + 81radical3) m^2
d. (270 pi +81radical3) m^2

D. (270 pi +81radical3) m^2

Step-by-step explanation:

In order to determine the area of the shaded region, we need to  

determine the area of the circle, the sector and the triangle  

that is a part of the sector. Do the following steps and work:

Area of the circle:

πr² = π(18)² = 324π

Area of the sector:

(60/360) (324π) = 54π

Area of the triangle:

60/2=30

1/2 (b)(h) = 1/2 (18cos30)(18) = 81√3

Area of the shaded region:

324π - 54π + 81√3 = 270π + 18√3

The answer is D. (270π + 18√3)m²

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
