Answer:
8 different choices
Step-by-step explanation:
With or without antibrake=2 ways
With or without player=2ways
With or without sunroof=2 ways
Total number of ways=2×2×2=8 ways
U/72 = 2/4
means u/72 = 0.5
therefore u = 72*0.5
which equals 36
Surface Area of Cylinder = 2πrh.
Radius, r = 7 cm, height = 12 cm.
Surface Area = 2*π*7* 12 = 168π cm²
π ≈ 3.14159
168π = 168*3.14159
Surface Area ≈ 527.79 cm²
Step-by-step explanation:
14 of 24 + 33 ÷ 9
336 + 33÷9
336 + 3.67
339.67
