Answer:
5.333 \pi
Step-by-step explanation:
Given is a function exponential as

The region bounded by the above curve, y =0 , x=4 is rotated about x axis.
The intersection of curve with x axis is at x=0
The limits for x are 0 and 4
The volume when rotated through x axis is found by

Here a = 0 and b =4
volume = 
=
I believe 6, if not i'm sorry but i think it really is 6
Answer: 7/8
Step-by-step explanation:
To find the equivalent expression of a fraction, we can either multiply numerator and denominator by same variable or same number, or we can divide both numerator and denominator by same number or same variable .
So if we multiply both numerator and denominator by 2, we will get

2) it is irrational and equal to 6 square root of 2
1. parallelograms
2. triangles
3. trapezoids
4. Circles
