Step-by-step explanation:
To find the Circumference of a triangle you use the formula C= 2(pi)r
in both of the problems you have the radius(r) and you plug the #'s in and solve
(pi)= 3.14...
#1.
2(pi)14.5
28(pi)
C= 87.92
#2.
2(pi)9.5
19(pi)
C= 56.66
The volume of the large cylinder will be twice the volume of the small cylinder.
<u>Step-by-step explanation:</u>
Let the radius of the cylinder be 'r'
Let the height of the cylinder be'h'
Volume of the small cylinder=π r² h
Volume of the large cylinder= π r² (2h)
Volume of large cylinder/volume of small cylinder= 2/1
The large cylinder volume is twice the volume of the small cylinder.
Answer:
x=2
Step-by-step explanation:
2.1(2.3 + 2.1x) = 11.65 + x
Distribute
4.83+4.41x=11.65+x
bring 4.83 over (-)
4.41x=6.82+x
bring x over
4.41x-1(x)=6.82
4.41-1=3.41 so
3.41x=6.82
divide 3.41
x=2
