A circle has a radius of 10. An arc in this circle
has a central angle of 72°
What is the length of the arc?
Either enter an exact answer in terms of tror
use 3.14 for and enter your answer as a
decimal.

The answer is 20 pi over 5

Step-by-step explanation:

You start by finding the circumference which you would get 20 pi by doing 2 times pi times your radius which is 10 then you find the fraction of the circle using the central angle which is 1/5 then you multiply 1/5 by 20 pi which you would put over 1 which then gives you 20 pi over 5

i just took the test, the correct answer is .. 31.5 in.

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.
