Answer:

Step-by-step explanation:
The formula of a volume of a cone:

r - radius
H - height
We have
r = (7 : 2) in = 3.5 in
H = 4 in
Substitute:


Answer:
55 degrees and 125 degrees
Step-by-step explanation:
Supplementary means that they add up to 180.
x + y = 180
Let's let x be the larger angle.
x = 15 + 2y
The above equation comes from the information given, that it's 15 more than twice the smaller angle.
Now let's use substitution.
x + y = 180
(15 + 2y) + y = 180
15 + 3y = 180
3y = 165
y = 55
The smaller angle is 55. Plug this back in to the first equation to get x.
x + y = 180
x + 55 = 180
x = 125
Now that you have both, test them again just to be sure that they fit the given conditions.
Monomial is one term, like #2 would be a monomial. binomial is two terms, like 3x - 2. trinomial is three terms, like #1,3,4. polynomial is four terms, like #5. standard form is just rewriting the equation in order from the term with the highest exponent to the lowest
Answer:
about 89.27 inches
Step-by-step explanation:
This is a right triangle question
c^2 = a^2 + b^2
c^2 = 15^2 + 88^2
c^2 = 225 + 7744
c^2 = 7969
Take the square root of both sides
c = 89.2692556259
c ≈ 89.27 inches
