Find the circumference of the circle 2.5cm Use 3.14 for pi.

15.7cm

Step-by-step explanation:

I'm going to assume the radius of the circle is 2.5cm:

The formula for circumference of a circle is C = 2πr...

So, C = 2 × 3.14 × 2.5

This makes the circumference of the circle 15.7cm. :)

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

see the picture for the graph.
