Answer:
x=6
Step-by-step explanation:
Since y=7 when x=2, we can from here simplify and see that y=3.5 when x=1. If y=21, then we multiply 7 by 3 which is 21, and since we must keep a proportion, we must multiply 2 by 3 and get 6 as the answer.
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.

I can't read the letters I the picture but it would be whichever square has sides that are 6 units long. This is because square a has sides that are 2 units long and dilating by 3 increases the square's size. 2×3= 6
