HEY THERE !!
As we know that the area of a circle (A)= πr^2
But if we know the diameter then the area is (A)= π/4× D^2 { here D is for diameter}
Here diameter is 10.5 inches.
A => π/4 × (10.5)^2
A => π/4 × 110.25
A => π/4 × 27.5625
A => 86.54625 { because the value of π = 3.14}
So the area of the cirsle whose diameter is 10.5 inches is 86.54625 inches square.
HOPE IT HELPED YOU.

is there any answer choices?
Edit: the answer is $339.79
"balance" means addition
Answer: perimeter = 302m
area = 5544m^2
Step-by-step explanation:
perimeter = 2(l + b)
= 2(63 + 88)
= 2 x 151
= 302 m
Area = l x b
= 88 x 63
= 5544 m^2
