Answer
Step-by-step explanation:
A=2πrh+2πr2=2·π·3·6+2·π·32≈169.646
When ever you combine different elements the chemical properties change because elements are different , unless you combine the exact same elements.
Answer:
Loss %age = 25%
Step-by-step explanation:
<u><em>Cost Price of Item</em></u> = 250,000/-
<u><em>Loss </em></u>= 1/4 = 0.25 of 250,000
=> 62,500 /-
<u><em>%age Loss</em></u> = 
=> 62,500 * 100 / 250,000
=> 6,250,000/250,000
=> 25 %
Answer:
Option (D)
Step-by-step explanation:
Length of the bar EG = 1.6x
If F is a point on the bar such that,
EF + FG = EG
Measure of segment EF = 6
Measure of FG = x
By substituting measures of each side,
6 + x = 1.6x
1.6x - x = 6
0.6x = 6
x = 10
Length of EG = x + 6
= 10 + 6
= 16 units
Option (D) will be the correct option.
Answer:

Step-by-step explanation:
We are given an expression and we have to transform it into an expression with exponent.
5th root of x can be written as 
![(\sqrt[5]{x^7})^3\\\\((x^7)^\frac{1}{5} )^3](https://tex.z-dn.net/?f=%28%5Csqrt%5B5%5D%7Bx%5E7%7D%29%5E3%5C%5C%5C%5C%28%28x%5E7%29%5E%5Cfrac%7B1%7D%7B5%7D%20%29%5E3)
The powers outside will be multiplied as: 

where the exponent is
and it is a rational number by definition of rational numbers
