Answer:
4.78 cm
Step-by-step explanation:
The formula for the volume of a cone of radius r and height h is
V = (1/3)πr²h. Here, V = 31.254 cm³ and r = 2.5 cm.
We begin by solving V = (1/3)πr²h for the unknown height, h:
31.254 cm³ 3(31.254 cm³) 93.762 cm³
h = ------------------------ = -------------------------- = -------------------- ≈ 4.78 cm
(1/3)πr² π(2.5 cm)² 19.635 cm²

Answer:
b=r-9/9
Step-by-step explanation:
First you do the distributive property...
r=9b+9
then you subtract the 9
r-9=9b
then you divide the 9
r-9/9=b
and because of the symetry property you can flip it...
b=r-9/9

Answer:
y=1250000
Step-by-step explanation:
Multiply 200000 by 1.25.
y = 250000 ⋅5
Multiply 250000 by 5.
y=1250000
