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.
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.
Ah, Area = pi R^2 (which is pi D^2/4)
Apologies for the confusion. You are correct.
The formula to find the area of a quarter circle is:
Area = (𝜋 * R^2) / 4
where R is the radius. Let's substitute the given value into the formula:
Area = (3.14 * 45^2) / 4
= (3.14 * 2025) / 4
= 6367.5 / 4
= 1591.88
Rounding to the nearest hundredth, the area of the quarter circle is approximately 1591.88 square millimeters.
What I am trying to say is
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.
To find the area of a quarter circle, we will use the formula:
Area = (𝜋 * r^2) / 4
where 𝜋 is the approximation of pi (3.14) and r is the radius.
Given that the radius is 45 millimeters, we can substitute the values into the formula:
Area = (3.14 * 45^2) / 4
Now, let's calculate:
Area = (3.14 * 2025) / 4
Area = 6356.25 / 4
Area = 1589.06
So, the quarter circle's area, rounded to the nearest hundredth, is approximately 1589.06 square millimeters.
To find the area of a quarter circle, we need to use the formula A = (π * r^2) / 4, where A represents the area and r is the radius.
Given that the radius of the quarter circle is 45 millimeters, we can substitute this value into the formula:
A = (3.14 * (45)^2) / 4
A = (3.14 * 2025) / 4
A = 6346.5 / 4
A = 1586.625
Rounded to the nearest hundredth, the area of the quarter circle is approximately 1586.63 square millimeters.
