Answer:
The Distance cover by boat in 2 hours and 15 minutes is 72 km
Step-by-step explanation:
Given as :
The Distance cover by boat = 128 kilometer
The time taken is 4 hours
As , Distance = Speed ×Time
So , Speed = 
Or, Speed = 
∴ Speed = 32 km per hour
Now, again The boat travel 2 hours and 15 minutes further with speed 32 kmph
So, Time2 = 2 +
Or, Time2 = 2 +
I.e Time2 =
hours
Again , Distance = Speed ×Time
So , Distance = 32kmph ×
hours
I.e Distance =
= 72 kilometer
Hence The Distance cover by boat in 2 hours and 15 minutes is 72 km Answer
Total cost of canvas required in making the tent is rupees 79128
<em><u>Solution:
</u></em>
Given:
Height of the cylindrical tent = h = 3.3 m
Diameter of it's base = d = 100m
r = 50 m
<em><u>Curved surface area of cylinder:</u></em>


Thus Curved surface area of cylinder = 1036.2 square meter
<em><u>Curved surface area of cone:</u></em>


Thus Curved surface area of cone = 8854.8 square meter
<em><u>Total curved area of tent:</u></em>
⇒ curved area of cone + curved area of cylinder

Thus total curved area of tent = 9891 square meter
<em><u>find total cost of canvas required in making the tent:</u></em>
The cost of canvas is 8 rupees per square meter

Thus total cost of canvas required in making the tent is rupees 79128
