There's a circle with that has a dot in the middle with two line going to the left and right that's is 16 m. I have to find the area of the circle. I have to give that exact area and an approximate area to the nearest square unit. Help?
Area = pi times radius squared
the radius Is squared
pi times 8 squared
use 3.14 for pi I u is not using calculator
To find the area of a circle, you first need to find the radius. In this case, you are given that the distance between the dot in the middle and either of the lines is 16 m.
The distance from the center of a circle to its edge is the radius. So, in this case, the radius of the circle would be 16 m.
Next, you can use the radius to find the area of the circle using the formula for the area of a circle: A = πr².
Multiply π (pi) by the square of the radius to find the exact area of the circle. Since π is an irrational number, your answer will most likely be in the form of π.
For example, if the radius is 16 m, the exact area of the circle would be A = π(16²) square meters.
To find the approximate area to the nearest square unit, you can use the value of π as approximately 3.14 or use the value provided in your math problem.
By substituting the values into the formula, you can calculate the approximate area of the circle.
