Question

4 cm Calculate the area of the circle. Use 3.14 for n. Round to the nearest tenth. a = [?] cm² Area of a Circle: A = πr² USE A​

Answer 1

The area of the circle is 50.2 cm².

Step-by-step explanation:

To calculate the area of a circle, you can use the formula A = πr², where A represents the area and r is the radius of the circle. In this case, the radius is given as 4 cm.

Using the value of π as 3.14, we substitute the values into the formula:

A = 3.14 x (4 cm)² = 3.14 x 16 cm² = 50.24 cm²

Now, to round to the nearest tenth, we look at the digit immediately after the tenths place, which is 2. Since it is less than 5, we round down the tenths place to get our final answer:

A = 50.2 cm²
