Find the area of the given circle. Round to the nearest tenth. theres a picture of a circle and the radius is 3.5

A. 22.0 cm squared
B.38.5 cm squared
C. 11.0 cm squared
D. 42.8 cm squared

May you explain it pls

A = pi * r^2

Area = pi * radius squared

so its 38.5 cm

Right.

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.

In this case, the radius of the circle is given as 3.5. So, to find the area, substitute the value of the radius into the formula:

A = π * (3.5)^2

Simplifying this equation, we get:

A = π * 12.25

Now, to find the rounded answer, you need to know the approximate value of π. The value of π is approximately 3.14.

A = 3.14 * 12.25

A ≈ 38.465

Rounding this value to the nearest tenth, we get:

A ≈ 38.5 cm²

Therefore, the area of the given circle, rounded to the nearest tenth, is 38.5 cm². So, the correct option is B. 38.5 cm².
