Answer:
Step-by-step explanation:
The angle of incidence and reflection is 45°
The angle between them is 90°
they lie on the same plane, and angle of incidence = angle of reflection
the sum of all the angles is 180°
let angle of incidence and reflection be x
therefore,
90 + 2x = 180
x = 45°
Answer:
9 cm
Step-by-step explanation:
V = 1/3 pi r^2 h
V = 1/3 * 3.14 * 5^2 * h
236 = 1/3 * 3.14 * 25 * h
236 = 26.1667 h
236 / 26.1667 = h
9.019 = h
Rounded to the nearest whole number the h is about 9 cm.
