Answer:
8.9
Step-by-step explanation:
hypotenuse (h) = 21
perpendicular (p) = 19
base (b) = x = ?
We know by using Pythagoras theorem
b = √h² - p²
x = √ 21² - 19²
x = √ 80
x = 8.9
Hope it will help :)
96π^2 = 947.48
π × r² × h
8π times 3*4*π
Answer: 24 pints
multiply the volume value by 8
3*8=24
x=20
