By the binomial theorem, the term in the expansion of is
which suggests that the contribution of the binomial coefficient should make up the remaining factor of 21. That is,
Answer:
Step-by-step explanation:
Volume of cylinder is given as
V is the volume the cylinder, r is its radius at the base, while is its height.
To select the formula for h (height) let's make h the subject of the formula as follows:
(dividing both sides of the equation by )
Use the formula above to find the height of the given cylinder where Volume (V) = 36π cm³, and base radius (r) = 3 cm:
(substitution)
( cancels )
