Find the area and circumference of a circle of 12 inches diameter

AREA!!!

To find the area of a circle, you use the equation pi r squared

since the diameter is 12, the radius is 6. So r squared is 36, multiplying that by pi we get inches squared.

CIRCUMFERENCE!!

The formula for finding the circumference is pi d or pi times diameter

Doing that we get inches squared.

Normally, schools and tests with have pi as 3.14, so you could add that into the equations, but only if it asks for you to. These solutions are only if the question didn't say anything about using 3.14 instead of pi.

Any questions?

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
