To find the area of a circle, you can use the formula A = πr^2, where A represents the area and r represents the radius of the circle.
Given that the radius is 14 cm, you can substitute this value into the formula:
A = π(14 cm)^2
To calculate the area, you need the value of π, which is approximately 3.14159. You can round this value to 3.14 for simplicity.
A = 3.14(14 cm)^2
= 3.14(196 cm^2)
= 615.44 cm^2
To round to the nearest tenth, you round the answer to one decimal place. Since the hundredth digit is 4, which is less than 5, you don't need to round up. Therefore, the final answer is 615.4 cm^2.
So, the correct answer is 615.4 cm^2, which is closest to the second option: 615.8 cm^2.
even easier is just to remember the formula for the area of a circle with radius r:
a = πr^2
Now just plug in your number
