Step-by-step explanation:

The formula for area of a circle is:

According to the word problem, the radius of the circle is 21 inches.

Now, we can just plug the numbers into the formula.

Therefore, the area of the circle is 1384.74 inches.

answer: the correct one is a

step-by-step explanation:

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
