A = pi * r^2
A = 3.14 * 2.5 * 2.5
A = ?
Multiply the area by 0.65
Thank you so much for the help! I understand what you did, and got the answer of 12.75625!
Yay! You're right.
To find 65% of the area of a circle with a diameter of 5, we can follow these steps:
Step 1: Find the radius:
The radius is half of the diameter. Since the diameter is given as 5, the radius would be 5/2 = 2.5.
Step 2: Calculate the area of the circle:
The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius. Substituting the value of the radius, we have:
A = π(2.5)^2
A = π(6.25)
A ≈ 19.63 (using π ≈ 3.14159)
Step 3: Find 65% of the area:
To find 65% of the area, we multiply the area by 0.65:
0.65 * 19.63 ≈ 12.75
Therefore, 65% of the area of a circle with a diameter of 5 is approximately 12.75.
