Find the area of the cone:
Area of cone: ⅓r^2h
⅓r^2h
= ⅓(3.5)^2(7)
= ⅓(12.25)(7)
= 1/3(85.75)
= 85.75/3
1/3 cup sloshed out:
(85.75/3 )/3
= 29.9 cubic cm
2x^2 + 3xy - 4y^2 when x = 2 and y = -4
= 2(2)^2 + 3(2)(-4) - 4(-4)^2 = 2(4) + (-24) - 4(16) = 8 - 24 - 64 = -80
Answer:
Q = 69.5 degrees
Step-by-step explanation:
3x + 14 + 3x - 27 = 180
6x - 13 = 180
6x = 193
x = 32.1667
Q = 3(32.1667) - 27
Q = 69.5
Answer:
the answer is 2 because between the points it goes up to and over 1 which make the slope 2/1 or 2.
Step-by-step explanation:
Answer:
Assuming the 4th coordinate is supposed to be (-1, -9) then the area is 18
Step-by-step explanation:
Plot it on a graph and it makes a very weird quadrilateral. But if the 4th coordinate (-1, 9)'s y coordinate is actual -9 then it makes a rectangle. I'm going to assume that's a typo and it is a rectangle so it would be a 3 by 6 rectangle. 3*6 is 18.
