Answer:
150.8
Step-by-step explanation:
Volume of big cylinder = pi * r^2 * h
small cylinder has a radius half the lenght of big cylinder, so height is also half of the big cylinder, since they are similar
so volume of small cylinder= pi * (r/2)^2 * h/2 = (pi * r^2 *h)/8= 1206/8= 150.75
UHHHHHHHH A AND UH C AND D?
To answer the 1 and 2 just put 0 on the variable other than the intercept you are looking for, if your looking for X, then Y = 0 so...
(Option D)1. -10x+5y=40
intercept on X
-10x + 5(0)=40
-10x=40 (divide by -10 to take x alone)
x= -4
intercept on Y
-10(0)+5y=40
5y=40 (divide by 5)
y=8
(Option D) 2. same procedure
int. X
5x +4y =80
5x + 4(0) = 80
x = 16
int y.
5(0) + 4y = 80
y = 20
3. just put in standard mode
y= (1/6)x + 4 (multiply by 6 so you have dont have fractions)
6y= x+ 24 (move x to the other side)
-x + 6y = 24
Answer:
5 x 199
Step-by-step explanation:
You can see that it is divisible by 5, a prime number, because it ends in 5. Once you divide it, you get 199 which itself is a prime number.
