Answer:
V≈339.3
Step-by-step explanation:
Formula for volume of a cylinder is
V=πr2h
if you plug in the numbers you get V≈339.29
Answer:
A is the anwer 99 degrees
D cause 51+51=102 because yeah I think thats how you do it
let's bear in mind that we have two fractions whose denominators are 2 and 4, thus their LCD will be 4, now let's multiply both side by that LCD to do away with the fractions, but let's add some first.
Answer:
y= -1 and x = 10
Step-by-step explanation:
(1) x+3y=7
(2) 2x-4y=24
Clear x from the 1st equation: x=7-3y
And replace x from the 2do one: 2(7-3y)-4y=24
14-6y-4y=24
-6y-4y=24-14
-10y=10
y=-10/10
y=-1
Now we have y=-1, let's finde x:
x=7-3y
x=7-3(-1)
x=7+3
x=10
