A wall clock has a circumference of 31.4 inches. What is the area of the clock use 3.14
The circumference of a circle is given by the formula C = 2πr, where C is the circumference, π is the mathematical constant pi (approximately 3.14), and r is the radius of the circle.
Given that the circumference of the clock is 31.4 inches, we can set up the equation:
31.4 = 2 * 3.14 * r
Solving for r, we get:
r = 31.4 / (2 * 3.14)
r = 31.4 / 6.28
r = 5 inches
Now that we have the radius of the clock, we can calculate the area using the formula for the area of a circle:
A = πr^2
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.5 square inches
Therefore, the area of the clock is 78.5 square inches.
