Question

Find the area of a circle with a radius of 30 cm (use π = 3.14). a) 2826 cm² b) 900 π cm² c) 904 cm² d) 188.4 cm²

Answer 1

The area of the circle with a radius of 30 cm is 2826 cm².

Step-by-step explanation:

To find the area of a circle, we use the formula A = πr^2, where A is the area and r is the radius. In this case, the radius is given as 30 cm. Plugging this value into the formula, we have:

1. A = 3.14 x (30 cm)^2
2. A = 3.14 x 900 cm^2
3. A = 2826 cm^2

Therefore, the area of the circle with a radius of 30 cm is 2826 cm², which is option a).
