Answer:
D) 25π/2 in²
Step-by-step explanation:
The area of a sector of central angle θ and radius r is ...
... A = (1/2)r²θ
Your sector has central angle π/4 and radius 10 in, so has area ...
... A = (1/2)(10 in)²(π/4)
... A = 25π/2 in² . . . . matches selection D
It's normally measured in pounds or kilograms.
A triangle has 3 sides so, to find the perimeter times 0.75 by 3
You get 2.25
