Answer:
The diameter would be 16
Step-by-step explanation:
The area of a circle is a=
×π. Now just plug in the values you have which is you area. 201=×π now divide by pi on both sides you that you get about 64=. Now find the square root on both sides which will then give you 8 as your radius. To find diameter from radius you have to multiply by 2. 8*2=16
Answer:
5.5%
Step-by-step explanation:
To find the interest rate, use the equation: I = prt
I = Interest = $6,600
p = principal = $15,000
r = rate = unknown
t = time = 8 years
Now plug the numbers into the equation.
6,600 = 15,000 * r * 8
6,600 = 120,000 * r
Now isolate the variable by dividing both sides of the equation by 120,000.
0.055 = r
Now change the rate to a percent by moving the decimal point 2 digits to the right.
5.5% = r OR r = 5.5%
Given:
The product of 
and 
greater than 5.
To find:
By how much the product of and greater than 5.
Solution:
First we need to find the product of and .
Now subtract 5 from the product.
Therefore, the product of and is 9.85 greater than 5.
