Find the area of the following plane figure. Use = 3.14.
A circle has a radius of 8 cm. What is its area?
Area (to the nearest tenth) =
201.0
To find the area of a circle, you can use the formula:
Area = π * radius^2
Given that the radius is 8 cm and π ≈ 3.14, we can substitute these values into the formula to find the area.
Area = 3.14 * (8 cm)^2
Simplifying the equation, we have:
Area = 3.14 * 64 cm^2
Calculating the expression:
Area = 200.96 cm^2
Therefore, the area of the circle with a radius of 8 cm is approximately 200.96 cm^2.
To find the area of a circle, we can use the formula:
Area = π * r^2
where π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
In this case, the radius of the circle is given as 8 cm.
Plugging the values into the formula, we have:
Area = 3.14 * (8 cm)^2
Simplifying the expression, we get:
Area = 3.14 * 64 cm^2
Calculating this, we have:
Area = 200.96 cm^2
Rounded to the nearest tenth, the area of the circle is approximately 200.96 cm^2.
