Question
A Toy is in the shape of a right circular cylinder with a hemisphere on one end and a cone on the other end. The height and radius of the cylindrical part are 13 cm and 5 cm respectively. The radii of hemispherical and conical parts are the same as that of the cylindrical part. Calculate the surface area of the toy if the height of the conical part is 12 cm
Hint:
Volume of cylinder 
The correct answer is: 770cm
Explanation:
- We have given A Toy is in the shape of a right circular cylinder with a hemisphere on one end and a cone on the other end. The height and radius of the cylindrical part are 13 cm and 5 cm respectively. The radii of hemispherical and conical parts are the same as that of the cylindrical part
- We have to find the surface area of the toy if the height of the conical part is 12 cm.
Step 1 of 1:
We have
Radius of base of the cylinder 5cm
Radius of base of the cone 5cm
Height of hemisphere = its radius = 5cm
Then
Total area of the toy = CSA of cone + CSA of cylinder + CSA of Hemisphere
