Hi there!
The formula for the area of a circle is A = pi x r^2. Using this formula, we can plug in the radius and solve for the area.
WORK:
A = pi x (5)^2
A = pi x 25
A = 25pi cm^2
ANSWER:
B - 25pi cm^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
The slope is the coefficient of x, regardless the order.
Step-by-step explanation:
Answer: x = 8, -4
Step-by-step explanation:
Square root of 21 is

I rounded it to 4.58
I'm assuming that you are trying to solve the equation for y, which we can do by isolating the variable on one side of the equation.
y/7 = 4
To get rid of the denominator of y, we have to multiply both sides by this amount (7).
(y/7)*(7) = (4)(7)
When we simplify, we get:
y = 28
If we go back to the original equation and plug in our answer, 28/7 = 4, we can see that it results in a true statement.
Therefore, the answer is y=28.
