Answer:
Lateral area=100 square inches
Step-by-step explanation:
It is given that the perimeter of the base of a pentagonal prism is 25 inches, therefore each sides of the pentagon will be of 5 inches.
Also, one of its lateral edge is 4 inches, therefore each lateral face has area which will be equal to=
=
square inches.
Since, there are 5 lateral faces of the pentagonal prism, therefore the lateral area of the prism will be: 
= 
square inches.
4 thousands = 4000
7 hundreds = 700
16 tens = 160
9 ones = 9
Then you add them all together:
4000 + 700 + 160 + 9
Your answer is 4869.
Answer:
answer = C
Step-by-step explanation:
If they directly tell you to round off once you have the answer, you should simply use a calculator but write out the actual value and write out the simplified one after it. I can't really see the question so I'll assume the first number should be 8. The answer is 1.165292268 but rounded off to 4 significant figures it's 1.1653. Hope this helps ;)
