Question

Identify the area of the circle. Use 22/7 for π

Answer 1

The area of the given circle is,

`A = 5819/350 cm^2 = 16.6257 cm^2`

Explanation:

Here, 4.6 cm is the diameter, d =4.6 cm

so, since the radius is d/2, we have,

r = 4.6/2 = 2.3

r = 2.3 cm

Now, the formula for area of a circle is,

A = π(r)^2 = π(r)(r)

Using 2.3 cm for r and 22/7 for π, we get,

`A = \pi r^2\\A = (22/7)(2.3)^2\\\\A = 5819/350 cm^2 = 16.6257 cm^2`

Hence we have found the area
