Answer: D) 452.16 square inches</h3>
==============================================================
Explanation:
The diameter is 24 inches, so the radius is half that at r = d/2 = 24/2 = 12 inches.
We'll use this along with the approximation pi = 3.14 to get the area
A = pi*r^2
A = 3.14*12^2
A = 452.16 square inches
Your teacher should have used "square inches" instead of "inches" as the unit.
We can abbreviate the "square inches" into "sq in" or "in^2".
This value is approximate since pi = 3.14 is approximate. Use more decimal digits of pi to find a more accurate value.
The exact area is 144pi
Answer:
D. 452.16 sq inches
Step-by-step explanation:
d = 24 ==> r = 24/2= 12 inches
the area = π×r²
= 3.14 × 12²
= 3.14 × 144
= 452.16 sq inches
