To solve this we are going to use the formula for the area of a circle: A= \frac{1}{4} \pi d^2
where
A is the area of the circle 
d is the diameter of the circle 

We know from our problem that the area of our circle is 10 inches long, so d=10in. Lets replace that value in our formula to find A:
A=\frac{1}{4} \pi (10in)^2
A=78.54in^2

We can conclude that the correct answer is: 78.54 square inches, or in centimeters: 506.7 square cm.

jeanine Baker makes floral arrangements. She has 13 different cut flowers and plans to use 7 of them. How many different selecti
Ksju [112]

A total of 1,716 selections of the 7 flowers are possible.

Step-by-step explanation:

Step 1:

There are 13 flowers from which Jeanine Baker plans to use 7 of them.

To determine the number of selections that are possible we use combinations.

The formula for combinations is; ^{n} C_{r}=\frac{n !}{(n-r) ! r !}.

Step 2:

In the given formula, n is the total number of options and r is the number of options to be selected.

For this question, n = 13 and r=7.

So ^{13} C_{7}=\frac{13 !}{(13-7) ! 7 !} = \frac{13 !}{(6) ! 7 !} = 1,716.

So a total of 1,716 selections are possible.
