Answer:
17
Step-by-step explanation:
Subtract 40 from s
-s=-17
Divide the negative sign
Divide by -1
-17 divided by -1 =17
Find the area of the 5 sides (not 6 because the top is open).
The area is made up of a load of rectangles. 2 of each rectangle are present except the top and bottom.
(4 x 2 x 2) + (3 x 2 x 2) + (3 x 4) = 40yd²
-1, 0, 1, 2... i believe those are the only integers
so the ice rink diameter is 80 feet what mean that the radius of ice rink is 40 feet
the walkway is 10 feet wide
so 10+40=50 what mean that the radius and the walkway wide make 50 feet length together
using this length area = pi*r^2 = 3,14*(50)^2 = 7850 feet squared
area of ice rink = 3,14*40^2 = 5024 feet squared
area of the walkway = 7850-5024 = 2826 feet squared
