Answer:
~8.7
Step-by-step explanation:
So we know that the formula for volume is 3.14 * r^2 * h.
So first we do 1738/23 to get an ugly ~ 75.6 Now he have to square root that to get r.
The square root of 75.6 is ~ 8.7

The expression for total number of points gained = 2x+17
Points earned for completing x levels = 4x+12.......(1)
Points lost in the video game = - (2x-5) [negative as they are lost]......(2)
Total Points gained = Algebraic sum of equation 1 and equation 2 =
(4x+12) + {- (2x-5) }
Hence the expression for net points earned now = 4x+12 -2x +5 = 2x+17
