Class 10 Maths MCQs for Surface Areas and Volumes

1. The shape of an ice-cream cone is a combination of:





Answer: d

2. If a cone is cut parallel to the base of it by a plane in two parts, then the shape of the top of the cone will be a:



(c)Cone itself


Answer: c

Explanation: If we cut a cone into two parts parallel to the base, then the shape of the upper part remains the same.

3. If we cut a cone in two parts by a plane parallel to the base, then the bottom part left over is the:


(b)Frustum of cone



Answer: b

Explanation: See the figure below
Surface areas and volumes MCQs

4. If r is the radius of the sphere, then the surface area of the sphere is given by;

(a)4 π r2

(b)2 π r2

(c)π r2

(d)4/3 π r2

Answer: a

5. If we change the shape of an object from a sphere to a cylinder, then volume of cylinder will



(c)Remains unchanged


Answer: c

Explanation: If we change the shape of a three dimensional object, the volume of the new shape will be same.

6. Fifteen solid spheres are made by melting a solid metallic cone of base diameter 2cm and height 15cm. The radius of each sphere is:





Answer: d

Explanation: Volume of ten sphere = Volume of cone

15×4/3 π r3= ⅓ πr2h

5×4 π r3=⅓ π 12(15)




7. The radius of top and bottom of a slant height 35 cm are 25 cm and 8cm. The curved surface of the bucket is:





Answer: c

Explanation: Curved surface of bucket = π(R1+R2) x slant height (l)

Curved Surface = (22/7) x (25+8) x 35

C.S = 22 x 33 x 5 = 3630 sq. cm.

8. If a cylinder is covered by two hemisphere shaped lid of equal shape, then the total curved surface area of the new object will be





Answer: c

Explanation: Curved surface area of cylinder = 2πrh

Curved surface area of hemisphere = 2πr2

Here, we have two hemisphere.

So, total curved surface area = 2πrh+2(2πr2) = 2πrh+4πr2

9. A tank is made of shape of cylinder with a hemispherical depression at one end. The height of cylinder is 1.45 m and radius is 30cm. The total surface area of tank is:





Answer: b

Explanation: Total surface area of tank = CSA of cylinder + CSA of hemisphere

= 2πrh + 2πr2= 2π r(h + r)

= 2 x 22/7 x 30(145+30) cm2

=33000 cm2

= 3.3 m2

10. If we join two hemispheres of same radius along their bases, then we get a;





Answer: c
