Question

What is the area of a circle with a diameter of 6?

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf{28.28 \: }}}}}`

Explanation:

Given, diameter of a circle = 6

pi ( π ) = 22 / 7

Finding the radius of the circle

We know that the radius of a circle is just half of the diameter. So, 6 / 2 = 3

Finding the area of circle having radius of 3

`\boxed{ \sf{area \: of \: circle = \pi \: {r}^(2) }}`

plug the values

⇒
`\sf{area \: of \: circle = (22)/(7) * {3}^(2) }`

Evaluate the power

⇒
`\sf{area \: of \: circle = (22)/(7) * 9}`

Calculate

⇒
`\sf{area \:of \: circle = 28.28 \: }`

Hope I helped!
