Answer:
angle B'CA'= angle BCA..... (common angle)
angle B'A'C = angle BAC.....(corresponding angels)
therefore,
ΔCB'A' ~ ΔCBA. ......(by A-A test of similarity)
therefore,
B'A'/ BA. = CA'/ CA....(congruent sides of congruent triangles)
now, B'A' = 5, CA'= 6 , CA = 6 + 3 = 9
5 / BA. = 6 / 9
therefore, 5 / BA. = 2 / 3

Answer : AB = 7.5 units
Answer:

Step-by-step explanation:
Given :
- Diameter of a drum = 20 inches
- Deep ( height ) of the drum = 16 inches
- π = 3.14
To Find:
The volume of the drum.
Solution:
We all know that drum is cylindrical.So we'll use the formulae of the volume of cylinder,to find its volume.

Where,
- r = radius
- h = height (deep)
- π = 3.14
The value of radius ain't given,but the diameter is given.We can use the formulae of radius.

Substitute the value of diameter:

Hence,the radius is 10.
So we could now use the formulae of the volume of cylinder:

- π = 3.14
- r =10 in
- h = 16 in
<em>[Firstly bring the answer in terms of π then plug π = 3.14 and then simplify.]</em>





<u>Hence, we can conclude that:</u>
The volume of this drum is 5024 in^3.
