Answer:
38 in
Step-by-step explanation:
P=w+w+h+h=18+18+6+6=26+12=38 in
Answer:
1 in. is the answer.
Step-by-step explanation:
Solution: A Rectangle ABDE in which DE=4 inches and BD= 6 inches
There are two kinds of rotations
1. one along the Breadth, side having length 6 inches,i.e rotated along line GH, Cylinder Z is created.
Radius of cylinder Z=6/2= 3 inches
2. Second along the Length, Side having length 4 inches,i.e rotated about a line CF, cylinder Y is created.
Radius of cylinder Y= 4/2= 2 inches
Difference in Radii= Radius of cylinder Z - Radius of cylinder Y
= 3 - 2= 1 inches
Diagram shown below of both the cases:
Answer:
48+x
Step-by-step explanation:
56-2(4+x)
56-8+x
48+x
The answer to this is x^2 + 2x - 5
