Step-by-step explanation:
area of a circle = pi times radius^2
254.34= 3.14 X r^2 get rid of 3.14 by dividing both sides by 3.14
254.34/3.14= r^2
81= r^2
find the square root of 81=9
2n(n + 3) - 5(n + 3) = (2n-5)(n+3)
A. (n + 3) (2n - 5)
Answer:
c
Step-by-step explanation:
Answer:
<u>Hours in first month = 8</u>
Step-by-step explanation:
AS it is given
He volunteered fr the first month = x hours

Total Hours volunteered = 40 hours
Now according to the given conditions
Volunteered first month + volunteered second month = total
putting this gives
x + 12/3 8 x = 40
as 12/3 = 4 so
it becomes
x + 4x = 40
solcing it will gives
5x = 40
x = 40/5
x = 8
