The formula to find the area of a quarter circle is:
Area = (𝜋 * r^2) / 4
where 𝜋 is the value of pi and r is the radius. Let's substitute the given values into the formula:
Area = (3.14 * 45^2) / 4
= (3.14 * 2025) / 4
= 6360.75 / 4
= 1590.19
Rounding to the nearest hundredth, the area of the quarter circle is approximately 1590.19 square millimeters.
The radius of a quarter circle is 45 millimeters. What is the quarter circle's area?
Use 3.14 for 𝜋 and round your answer to the nearest hundredth.

Ah, Area = pi R^2 (which is pi D^2/4)
Apologies for the confusion. You are correct.

What I am trying to say is
Area of circle A = pi R^2
then later area of quarter circle = A / 4
Area of circle A = pi R^2
then later area of quarter circle = A / 4
Apologies for misunderstanding your earlier statement. You are correct. The formula to find the area of a quarter circle is:
A = (π * R^2) / 4
where A is the area and R is the radius. Let's calculate the area:
A = (3.14 * 45^2) / 4
= (3.14 * 2025) / 4
= 6368.25 / 4
= 1592.06
Rounding to the nearest hundredth, the area of the quarter circle is approximately 1592.06 square millimeters.
