Question

PLS HELP

a circle has a diameter of 8 meters find the approximate area of the circle and use 3.14 for pi

Answer 1

50.24

Explanation:

Your first mistake that you made was in the third step. You seem to have made the mistake by multiplying 3.14 which gave you the answer 25.12. A suggestion I would make for you would be to first get your correct equation which in this case is finding the radius of 8 which gives you the answer of 4 then multiply it by 3.14 which gives you the answer to 50.24 meters2

Answer 2

A = 50.24 m^2

Explanation:

1) The mistake occurred between:

A = 3.14(4^2)

A = 3.14(8)

What you did was mistakenly (4^2) as 4 * 2 which equals 8.

The equation wants you to take the radius number and times it by itself thus:

4 * 4 which would equal 16.

Therefore, A = 3.14(16) which will equal 50.24 m^2

(# = number)

2) The #^2 can be tricky and if not paying attention to your work, it can be assumed accidentally as # * 2.

I recommend taking it slow and double-checking your work to make sure everything is on track, especially when solving equations that require a lot of work to be done.

Hope this helps :)
