Answer:
4.835(I don't know unit.(m/in/cm)
Step-by-step explanation:
volume=πr^2h
136.78=22÷7×3^2×h
h=136.78×7÷(22×9)=4.835
Answer:
3(4+3x)
Step-by-step explanation:
See Image below.
here's the solution,
we know :

So,

so.. let the perpendicular be 12x and hypotenuse be 13x
now,
by applying pythagoras theorem,
where,
- b = base
- h = hypotenuse
- p = perpendicular
So,
so,
hope it helps !!
