Answer:
It travels 1/5 mile in one second
Step-by-step explanation:
1/10 * 2 = 2/10 = 1/5
Since the bolt of lightning travels 1/10 mile in half a second, then to find how much it travels in one a second you simply multiply 1/10 by 2, which equals 2/10, which can be simplified to 1/5.
Find the volumen of the semisphere and subtract the volumes of the two cylinders
1) Volume of the semisphere:
[1/2] (4/3)π(r^3) =[ 2π(1.5m)^3 ]/3 = 7.0686 m^3
2) Volumen of the cylinders:π(r^2)h
a) π(0.75/2m)^2 (1.75m) = 0.7731 m^3
b) π(1/2m)^2 (1.25m) = 0.9818 m^3
3) 7.0686 m^3 - 0.7731 m^3 - 0.9818m^3 = 5.3137 m^3
Answer: 5.3 m^3
