Answer:
62.84
Step-by-step explanation:
pie=3.142
c=pie * diameter
r=10cm
d=2r
d=2(10)=20cm
c=3.142 * 20
c=62.84
X=1 and y=4. first I did
3x+2y=11
y=5x-1
and 3x+2(5x-1)=11
=3x+10x-2=11
=13x-2=11
cancel 2 out
13x=13
x=1. then simply add x in the original y equation,
y=5x-1
y=5(1)-1
y=5-1
y=4.
check your work
3(1)+2(4)=11
4=5(1)-1
again X=1 AND Y=4
Hope this helped
Answer:
Volume = 14,836.5 cubic inches
Step-by-step explanation:
Cylinder not shown but information given. So we will calculate the volume.
Volume of Cylinder is given by the formula:

Where
V is the volume
r is the radius (HALF of DIAMETER)
h is the height
It is given in the problem,
Height is 21
h = 21
and
half the diamter (aka radius) is 15
r = 15
Substituting into formula and using 3.14 for
, we get the volume:

Hence, the volume is:
Volume = 14,836.5 cubic inches
Answer:
1) 9
