The radius of a circle is 7 in. what is the circumference?

Remember the formula for the circumference of a circle:

We know that the radius of this circle is 7 in. So, let's plug it into the formula:

C≈44 in (Answer)

Hope it helps ~

the solution is h=10 because you add 9 to each side of the equation.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
