problem solving:
find the area of the clock with the radius of 8 centimeters.
well, the area of a circle with radius r is πr^2, so ...
To find the area of the clock, you can use the formula for the area of a circle:
Area = π * radius^2
Given that the radius of the clock is 8 centimeters, we can substitute this value into the formula:
Area = π * 8^2
To find the value of π (pi), we can use an approximate value of 3.14. Hence:
Area = 3.14 * 8^2
Next, we can calculate the square of the radius:
Area = 3.14 * 64
Now, let's multiply the values:
Area ≈ 201.06 square centimeters
Therefore, the approximate area of the clock is 201.06 square centimeters.
To solve this problem, we need to know the formula for finding the area of a circle. The formula for the area of a circle is A = π * r^2, where A represents the area and r represents the radius.
In this case, we are given that the radius of the clock is 8 centimeters. So, we can substitute this value into the formula to find the area.
A = π * (8 cm)^2
A = π * 64 cm^2
A ≈ 200.96 cm^2
Therefore, the area of the clock is approximately 200.96 square centimeters.
