Answer:
V =9.42 in^3
Step-by-step explanation:
The diameter is 3 inches
The radius is d/2 = 3/2 inches
The volume is
V = 4/3 pi r^2
V = 4/3 ( 3.14) ( 3/2) ^2
V =9.42 in^3
Answer:
1) 3/2
2) 13/10
3) 1/3
4) 9/7
5) 13/20
Step-by-step explanation:
Answer:
314.2in^2
Step-by-step explanation:
GIven data
diameter= 10in
radius= 5in
Height= 2in
The expression for the curved surface area (CSA) of a cylinder is given as
CSA=2πrh
CSA=2*3.142*5*2
CSA=62.84 in^2
The material needed to make one pipe is 62.84in^2
Hence the material need for 5 pipes is
=62.84*5
=314.2in^2
we are given
to write the sets of points from -2 to 5 but excluding 2 and 5 as a union of intervals
so, first interval is
-2 to 2 by excluding 2
[-2,2)
Second interval is
2 to 5 by excluding 2 and 5
so, we can write as
(2,5)
now, we can find total interval
we get
[-2,2) ∪ (2,5)..............Answer
Answer:
5/8 inch
Step-by-step explanation:
Find the difference between 1 inch and 3/8 inch.
= 1 - 3/8
= 8/8 - 3/8
= 5/8 inch
