The area of a circle depends on the radius. Use the equation A(r) = 3.14 r2 to compute A(8). Round your answer to the nearest hundredth.
To compute A(8) using the equation A(r) = 3.14 * r^2, where r is the radius of the circle, you need to substitute the value of r with 8 and then perform the calculations.
Step 1: Substitute the value of r into the equation.
A(8) = 3.14 * 8^2
Step 2: Simplify the equation.
A(8) = 3.14 * 64
Step 3: Calculate the result.
A(8) = 200.96
Therefore, the area of the circle with a radius of 8 units is approximately 200.96 square units when rounded to the nearest hundredth.
Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
Area = π r^2 = 3.14 * 8 * 8
You do the math.
