What is the radius of a circle with an area of 49 pi
1 answer:
Answer:
r = 7
Step-by-step explanation:
The area of a circle is given by the equation A = πr²
We need to manipulate the equation and solve for r
First we need to divide both sides by π and we get 
We then need to take the square root of both sides to get r by itself which give us 
Now plugging in our known values we can solve for r

Simplifying gives us the result of the radius being 7 square units

Answer:
187
Step-by-step explanation:
a=12,d=17-12=5
nth term =a+(n-1)d
36th term=12+(36-1)5
=12+(35×5)
12+175
36th term=187
