Answer:
About 50.14 Centimeters
Step-by-step explanation:
The formula for the volume of a cylinder is:

Now, let's plug in the values. (We'll use 3.14 for pi.)

All we do now, is solve for r. Divide 76 on both sides...

Divide 3.14 on both sides...

Lastly, find the square root on both sides.


Therefore, the r, or the radius, is around 50.14 centimeters. Hope this helps!
Given:
Principal = Rs. 2000
Rate of interest = 20% p.a. compounded quarterly.
Time = 1 year
To find:
The compound interest.
Solution:
Formula for amount:

where,
P = Principal
r = Rate of interest
t= Time
n = number of times interest compounded in an year.
Putting P=2000, r=0.2, n=4 and t=1, we get




Now, the compound interest is



Therefore, the compound interest is Rs 431.0125.
The circumference of a circle is calculated using the following equation:

Where d is equal to the diameter (the length of a straight line from one side of the circle to the other side).
We know that the diameter of the circle given (also known as AB) is equal to 20 cm.
We can then plug this into the equation and solve for the circumference:

Since the question asks for the answer to be in terms of

, this is as far as we need to go. So
the circumference of the circle is:
or D.
