Answer:
The volume of the figure is
Step-by-step explanation:
we know that
The volume of the figure is equal to the volume of the cone minus the volume of the square pyramid
step 1
Find the volume of the cone
The volume of the cone is equal to
we have
----> the diagonal of the square base of pyramid is equal to the diameter of the cone
substitute
step 2
Find the volume of the square pyramid
The volume of the pyramid is equal to
where
B is the area of the base
h is the height of the pyramid
we have
substitute
step 3
Find the volume of the figure
Y = mx + b
slope(m) = 3/4
(-8,7)...x = -8 and y = 7
now we sub and solve for b, the y int
7 = 3/4(-8) + b
7 = - 6 + b
7 + 6 = b
13 = b
so ur line is : y = 3/4x + 13
Answer:
im sorry im just answereing like this to complete challenges but im heping people i understand the problems of.
Step-by-step explanation:
A) You're just plugging in an "x" into the given equation here, and you need 8. I'd go with numbers that divide into whole integers by 8 (e.g. -4, -2, 2, 4), write down the x, then "y" after plugging into the equation.
B) Plot the coordinates you got from the first problem.
C) Any linear function has the domain of all real numbers, meaning that you can plug in any "x" and it'll work. What if you have a rational (something in the denominator) function though and x is in the denominator? Well, if we plug in any number and divide by 8, it works, BESIDES 0. You cannot divide by zero, and we call this "undefined" in math. There is no definitive nor quantitative answer, it is simply "undefined" because you can't divide something by 0
C = 2(3.14) x r
C = 6.28 x 10
C = 62.8 yards
