The formula for this is
. If the diameter is 8 the radius is 4, so filling in accordingly we have
and
which is
and when you multiply in 3.14 you get that A = 401.92 or B above.
Answer:
22.5 cm
Step-by-step explanation:
We know, that the formula for the circumference of a circle is d*pi or 2 * r * pi
So we know 45 = diameter. Meaning r = 22.5
Hi there!
With exponents, there are a few things to keep in mind:
1. Do <u>not </u>multiply the base by the exponent (the base is the number that has an exponent; for example, 3 is the base of 3^2)
2. On the computer, exponents are signaled by this sign ^.
3. The exponent is the number of times you multiply the base by itself
Let's say you're given this exponent : 6^3
Because the exponent is 3, we need to multiply 6 by 6 a total of 3 times. It's tricky, but here's how you do it:
(6 * 6) * 6
36 * 6 = 216
So, 6^3 is 216
Here's another example:
9^5
(9*9) * 9* 9* 9
[81 * 9]*9 *9
[729 * 9] * 9
6561 * 9
59049
There is 140% increase.
Step-by-step explanation:
Given,
10 gallons to 24 gallons
Old value = 10 gallons
New value = 24 gallons
Change = New value - Old value
Change = 24 - 10 = +14
The positive sign indicates the increase.
Percent increase = 
Percent increase = 
Percent increase = 140%
There is 140% increase.

Answer:
y = (3/2)x - 4
Step-by-step explanation:
Use (y2-y1)/(x2-x1) to find slope, and then y-intercept is -4.
