I attached an image with the complete question.
Answer:volume of attic = 1526.04 ft³
Explanation:Volume of cone can be calculated using the following rule:
Volume =

* area of base * height
Volume =

* π * radius² * height
We are given that:
π = 3.14
radius = 18/2 = 9 ft
height = 18 ft
Substitute in the equation to get the volume as follows:
Volume =

* 3.14 * (9)^2 * (18) = 1526.04 ft³
Hope this helps :)
Answer:
yea by using a resipe
Step-by-step explanation:
Answer:
y=3x-7
step by step explaination:
The main idea here is to "translate" the words into maths.
First we need to identify the unknowns and label these.
We need to know the number if dimes and the number of quarters. So lets say
x: number of dimes
y: number of quarters
Now lets write equations from the written problem.
We know that there are 36 coind total, thus:
x + y = 36
We also know that the coins total 5.85 dollars, but it is better to count in cents, that is 585 cents.
x are the number of dimes, their value is x*10
y are quarters with value of y*25
thus:
10x+25y=585
We have two equations and two unknowns now, that needs to be solved to get the answer.
x + y = 36
10x+25y=585
If the two angles of the triangle are equal. Well yes, because if the angles are both 50 degrees then the other angle will be 30. but it also depends on the shape of the triangle if they differ.
