Question

The face of a clock has a circumference of 63 in. What is the area of the face of the clock?

Answer 1

The answer is 316

Explanation:

I did a test it is the right answer everyone els is wrong :/

Answer 2

The area of the clock
`= 315.41\ inch^(2)`

Explanation:

We have been given the face of the clock that is
`63\ in`

So that is also the circumference of the clock.

Since the clock is circular in shape.

So
`2\pi(r)=63\ inch`

From here we will calculate the value of radius
`(r)` of the clock that is circular in shape.

Then
`2\pi(r)=63\ inch =(63)/(2\pi) = 10.02\ in`

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now
`\pi (r)^(2)=\pi(10.02)^(2)=315.41\ in^(2)`

So the area of the face of the clock =
`315.41\ in^(2)`
