find the area of the circle to the nearest tenth...3.7m is the radius.
Area = pi * r^2
r^2 = radius squared
pi = 3.1416
Put values into formula to solve.

To find the area of a circle, you can use the formula: A = πr^2.
Given that the radius (r) is 3.7m, we can substitute this value into the formula and calculate the area (A):
A = π(3.7)^2
A ≈ 3.14 * (3.7^2)
A ≈ 3.14 * 13.69
A ≈ 42.9746
Rounded to the nearest tenth, the area of the circle is approximately 43.0 square meters.
To find the area of a circle, you can use the formula A = πr², where A represents the area and r is the radius of the circle.
Given that the radius is 3.7m, we can substitute this value into the formula:
A = π(3.7)²
To get the answer to the nearest tenth, we need to calculate the value of the expression. Let's break down the steps:
Step 1: Calculate the square of the radius:
(3.7)² = 13.69
Step 2: Multiply the squared radius by π (pi):
A = π * 13.69
Step 3: Use an approximation for the value of pi, which is commonly taken as 3.14:
A ≈ 3.14 * 13.69
Step 4: Calculate the final result:
A ≈ 43.003
Rounding to the nearest tenth, we get:
A ≈ 43.0 square meters
Therefore, the area of the circle, to the nearest tenth, is 43.0 square meters.
