Answer:
8.06
Step-by-step explanation:
3.5^2 + 2^2 = 16.25
sqrt(16.25) = 4.03112887
2 * 4.03112887 = 8.06225774
8.06
A square has 4 sides, so 128 in. Squared divided by the 4 sides, would then equal 32 in. Squared for the approximate side length of a square game board
Circumference = 2πr
Our cylinder's circumference: 2 * π * 9 = 18π
Surface area of cross section = πr² = π * 9² = 81π
* 2 since there is two cross sections: 81π * 2 = 162π
Surface area of rounded face, treat it like a rectangle: C*H
18π * 11 = 198π
Add the surface areas, 198π + 162π = 360π in²
BD = BC + CD
7x - 10 = (4x - 29) + (5x - 9)
7x - 10 = 9x - 38
2x = 28
Ans: x = 14
BC = 4x - 29
= 4(14) - 29
= 27
Ans: BC = 27
CD = 5x - 9
= 5(14) - 9
= 61
Ans: CD = 61
BD = 61 + 27
= 88
Ans: BD = 88
