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
Answer:

y
Step-by-step explanation:
(think about it with a horizontal line between the two numbers)
When using fractions and whole numbers turn the whole numbers into fractions like ---> 3/1
and if their like 3 5/6 (for example) you would multiply the denominator by the whole number ---> 3*6=18 then add what's on the numerator with it. so 18+5=23 which would make it 23/6
Just some tips for making it easier!
Hope it helps! :)
