Answer:
87.28 cubic inches
Step-by-step explanation:
Leigh wants to fill the conical candle wax mold completely with candle wax.
We have to calculate the volume of the cone by the formula :
Here, V = volume
r = radius = 2.1 inches
h = height = 18.9 inches
By substituting these values given, into the formula
= (27.783)π
= 87.28 inch³
Conical mold can hold 87.28 inch³ candle wax.
Answer:
Final answer is .
Step-by-step explanation:
Given expression is .
Now we need to find about what value for c will make the given expression , a perfect square trinominal.
Coefficient of middle term that contains x, in -7.
Take half of that so we get .
Then take square of the half value.
We get .
We add the square value to make perfect square trinomial.
Hence final answer is .
