Answer:
15
Step-by-step explanation:
Ok so first you need to know how to calculate the volume of a cylinder
I will put the formula here: V=πr2h
Since pi is equal to 3.14 as said in the problem we can simply divide 282.6 by pi, the radius and 2
That is equal to 282.6/3.14*3*2
A little calculation shows that, the answer is 15
Hope this helps :)
Answer:
9 sides.
Step-by-step explanation:
N is the # of sides.
140 = ((n-2) x 180) / n
Multiply both sides by n
140 n = (n-2) x 180
Distribute the right side
140 n = 180 n - 360
Subtract 140 n and add 360 to both sides.
40 n = 360
n = 9
Answer:
there is a 1 to 15 relationship between miles and gallons
Step-by-step explanation:
TanY=y/x
cotY=1/tanY
cotY=x/y
Step-by-step explanation:
No. of points got from 1 stunt = 50.
No. of points deducted from 1 fail = 40.
6 stunts and 9 falls were gained last week.
So, A/C the number of points earned =
(6×50)-(9×40)
= 300 - 360
= -60
Her score today is 3 times her score from last week so multiply by 3
= (-60) × 3
= -180
If it were multiplied by -3 instead of 3 it would be...
(-60) × (-3)
= 180
The difference would be that on multiplying with positive 3 she would be 180 points in the whole but multiplying with negative three means she is 180 points in the league.
The similarity is that that whole number is same but the symbol adds a difference and the absolute value would be same too.
