Answer: C . 147π / 4 mi²
Concept:
The sector is the part of a circle is enclosed by two radii of a circle and their intercepted arc.
A = (θ / 360) πr²
θ = angle of the sector
π = constant
r = radius
Solve:
<u>Given variable</u>
θ = 270°
r = 7 mi
<u>Given formula</u>
A = (θ / 360) πr²
<u>Substitute values into the formula</u>
A = (270 / 360) π (7)²
<u>Simplify exponents</u>
A = (270 / 360) π 49
<u>Simplify by multiplication</u>
A = (147 / 4) π
A = 147π / 4
Hope this helps!! :)

Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below =)
All you need to do is use the formula to solve. What I do is I plug in the information that I know, and then I just solve. In this case it would be:
V= (4)
- pie(3.14)*4.8(cubed)
