B.
if you plug it in your answer would be 10
Answer:
Radius: 18
Area of Circle: 1017 or 1018(depends on whether you used the pi function or 3.14)
Step-by-step explanation:
Formula for the circumference and area:
C= 2πr
A= πr^2
2 less than (3 times a number) is the same as (the number plus 10)
2 less than (3*x) = (x + 10)
3x - 2 = x + 10
From here, you solve! :)
3x - 2 - x = x + 10 - x
2x - 2 = 10
2x - 2 + 2 = 10 + 2
2x = 12
2x / 2 = 12 / 2
x = 6
Hope this helps! :)
