Answer:
398in2
Step-by-step explanation:
Surface area formula for a rectangular prism = A = 2(wl + hl + wh)
2(width*length)(height*length)(width*height)
L= 9
W= 5
H= 11
A=2(wl+hl+hw)=2·(5·9+11·9+11·5)=398

Answer:
x=22
Step-by-step explanation:
4x+2+x+3x+2=180
collect like terms
4x+x+3x=180-(2+2)
8x=180-4
8x=176
make x the subject of the formula
x=176/8
x=22

Answer:
700π m ~ 2199 m
Step-by-step explanation:
diameter = d = 200 m
2 min 20s = 140 s
1 round / 40 s
140 = 40 * 3 + 20
so the athlete will cover 3 round and half
1 round = d * π
covered = c = 3 * 200 * π + 200/2 * π = 700 * π
