Answer:
45
Step-by-step explanation:
4/5 t = 36
Divide both sides by 4/5
4/5 / 4/5 t = 36/4/5
4/5 cancels 4/5
Also flip the divisor 4/5
t = 36x5 / 4
= 180/4
= 45

Answer:
12 units
Step-by-step explanation:
The formula for the volume of a cone is given as:
πr²h/3
The volume = 100π cubic units
Diameter = 10 units.
Radius = Diameter/2
= 10 units/2 = 5 units
Hence:
Formula to find the height of a cone
h = 3V/πr²
We substitute
h = 3 × 100π/π × 5²
h = 300π/25π
h = 12 units
The height = 12 units
