Answer:
Do you know the cylinder volume formula?Answer is: V=Pi*r^2*h Let me explain what that means. So the Pi is a constant number equal to 3.14..... and continue and this doesn't effect the volume while radius and height are the ones who do that.The volume is more effected by the radius because if both of them are a same number the radius would be greater than the height.
If r= 2 and h=2 than V=Pi*2^2*2 V=3.14*4*2
Step-by-step explanation:
Let me solve the problem!
a) r=3 h=10 than V=Pi*3^2*10 V=Pi*9*10 V=90Pi
When we increase the raduis by 1
b)r=4 h=10
V=Pi*4^2*10 so V=Pi*16*10 so V=160Pi
c)r=3 h=11
V=Pi*3^2*11 so V=Pi*9*11 so V=99Pi
It meas that when the radius is increased by 1inc the volume is greater than when you increase the height by 1.

Eliminate x's by adding te 2 equations
add them
-2x+15y=24
<u>2x+9y=24 +</u>
0x+24y=48
24y=48
divide both sides by 24
y=2
sub back
2x+9y=24
2x+9(2)=24
2x+18=24
minus 18 both sides
2x=6
divide 2
x=3
x=3
y=2
(x,y)
(3,2)
Answer:
21 m
Step-by-step explanation:
P= a+b+c
so it be 9+7.5+4.5 = 21
9-1.5 = 7.5
9/2 = 4.5
Answer:
third number = 4,
equation of y, y = 5x - 11
equation of n, n = 4x
equation of x, n + x + y =19
Step-by-step explanation:
so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19
10x = 30
x = 3.
Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11
15 - 11
4 = third number
Answer:
z = -9.538546756+ 15.26486573i
Step-by-step explanation:
z = |z| cos theta + |z| i sin theta
We know |z| and theta
z = 18 cos 122 +18i sin 122
z = -9.538546756+ 15.26486573i
