Answer:0.5
Step-by-step explanation:
<u>Given</u>:
The radius of the figure is 5 mm
The height of the cylinder is 9 mm.
Volume of the composite figure is made of two half spheres and a cylinder.
We need to determine the volume of the composite figure.
<u>Volume of a cylinder:</u>
Volume of a cylinder is given by
Substituting r= 5, h = 9, we get;
Thus, the volume of the cylinder is 706.5 mm³
<u>Volume of the hemisphere:</u>
Volume of the hemisphere is given by
Substituting r = 5, we get;
Thus, the volume of the hemisphere is 261.67 mm³
<u>Volume of the composite figure:</u>
The volume of the composite figure can be determined by adding the volume of the cylinder and 2 hemispheres.
Thus, we have;
Thus, the volume of the composite figure is 1229.84 mm³
The opposite of -3/8 is 3/8 and the opposite of that is -3/8.
The answer is -3/8
Given:
- Bought n items of product A at 1/5 rs each
- bought n items of product B at 1/4 rs each
He mixed the two items and sold each at 2/9 rs each.
He lost 3 rs in the above batch of articles.
Solution:
revenue = 2n* (2/9) rs = 4n/9 rs
cost = n/5+n/4 rs = n(1/5+1/4)
Profit = revenue-cost = 4n/9-n(1/5+1/4) = -3 rs
Solve for n
4n/9-n(1/5+1/4) = -3
factor out n
n(4/9-1/5-1/4)=-3
n(80-36-45)/180=-3
-n/180=-3
n=3*180=540
Total number of products bought
= n+n = 540+540 = 1080
