Find the area of the given circle. round to the nearest tenth
The area of a circle is equal to pi times the radius squared.
If the radius of the circle is 5, then the area of the circle is 78.5 (pi x 5^2 = 78.5).
To find the area of a circle, you need to know the radius or the diameter of the circle. The formula for the area of a circle is:
Area = π × r^2
Where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.
If you have the radius of the circle, you can directly substitute it into the formula to find the area. However, if you have the diameter instead, you need to first convert it to the radius by dividing it by 2.
Let's assume you have the radius of the circle. To find the area, follow these steps:
1. Square the radius by multiplying it by itself.
2. Multiply the squared radius by π (pi).
3. Round the result to the nearest tenth.
For example, let's say the given radius of the circle is 5 units. Using the formula:
Area = π × (5)^2
Area = π × 25
Area ≈ 3.14159 × 25
Area ≈ 78.54
Rounding to the nearest tenth, the area of the circle is approximately 78.5 square units.
