These two cylinders are congruent. cylinder a has a radius of 4 centimeters. cylinder b has a volume of 176π cubic centimeters.
2 answers:
The height of cylinder b is 11 cm.
<h3>How to measure the volume of a cylinder?</h3>The volume of the cylinder is related to the capacity of this geometric figure. Remember that the cylinder or circular cylinder is an elongated and rounded geometric solid.
The formula for the volume of a cylinder is given by:
Where:
- V: volume
- π (Pi): 3
- r: radius
- h: height
In this case, as the cylinders are congruent, both will have the same radius, thus:

Solution:
Principal =P= $ 7,500
Option A→(Simple interest)
Rate of interest= R=4%
Time()=4 years
Time()=6 years
Amount= Principal + Interest(Simple or compound interest)
Formula for Simple interest
Total amount after 4 years when interest is simple= 7500 +1200= $ 8700
Total amount after 6 years when interest is simple= 7500 +1800= $ 9300
Option B
Formula for amount(A) when interest is 3.15% compounded annually.
Total amount after 4 years when interest is compounded annually=$ 8491 (approx)
Total amount after 6 years when interest is compounded annually=$ 9034(approx)
