Answer:
c
Step-by-step explanation:
volume of cylinder = πr^2h
r = 6.5
h = 13+13+13 = 39
cylinder volume = 1647.75π cm^3
volume of one sphere = 4/3 π r^3
= 366.16π cm^3
space not occupied by tennis balls = 1647.75π-3(366.16π)=549.25π cm^3
Answer:
the answer for your question is b
This is Pythagorean theorem, a^2+b^2=c^2 , a = 33 and c = 37 so b^2 + 1089 = 1369 , b^2 = 280 , b = 16.73m
Answer:
The youth group bought 35 geraniums and 45 daisy plants.
Step-by-step explanation:
We can solve this using a system of equations:
x + y = 80
4x + 6y = 410
X = Geraniums
Y = Daisies
First, let's solve for a variable in the first equation. I am going to solve for y in the first equation:
x + y = 80
y = -x + 80
Now that we have solved for y we can plug that back in to the 2nd equation:
4x + 6(-x + 80) = 410
4x - 6x + 480 = 410
-2x + 480 = 410
-2x = -70
x = 35
Now that we have found the amount of geraniums we can plug it back into the first equation and solve for y:
35 + y = 80
y = 45
Therefore the youth group bought 35 geraniums and 45 daisy plants.
Check:
(35) + (45) = 80
80 = 80
4(35) + 6(45) = 410
140 + 270 = 410
410 = 410
