Radius of cone is2.39cmor 2.4cm
volume of cone=45.19cm^3
Pi×r^2×h/3=45.19
22×r^2×7.5/7=45.19×3
r^2=45.19×3×7/22×7.5
r^2=948.99/165
r^2=5.7514545
r=2.39
Or we can say r=2.4cm
Answer:
Yes
Step-by-step explanation:
9/15 divided by 3/3 = 3/5
therefore yes.
Answer:
<h2>(-2, -4)</h2>
Step-by-step explanation:
Put the coordinates of the points to the equation, and check it:
(-4, -1) → x= -4, y = -1
L = -5(-4) - 3(-1) =20 + 3 = 23
R = 22
L ≠ R
(-1, -4) → x= -1, y = -4
L = -5(-1) - 3(-4) = 5 + 12 = 17
R = 22
L ≠ R
(-2, -4) → x= -2, y = -4
L = -5(-2) - 3(-4) = 10 + 12 = 22
R = 22
L = R CORRECT :)
(-4, -2) → x = -4, y = -2
L = -5(-4) - 3(-2) = 20 + 6 = 26
R = 22
L ≠ R
Answer:
-2x+8
Step-by-step explanation:
-2(x-4)
Distribute
-2*x -2*-4
-2x+8
Solve x by simplifying both sides of the equation, then isolating the variable.
Answer:
x= - 31/2
