Geometry is the branch of mathematics that is concerned with the shapes and sizes of different figures. Given below are 8 Base MCQs on Geometry.

Area of a circle having radius 15 is:

- 148
- 706
- 23.5
- 1413

Correct answer: 2. 706

*Explanation: Area of circle = πr*^{2}* = 3.1416 * 15 * 15 = 706 approx*

The volume of a sphere having radius 20 is:

- 28
- 50265
- 84
- 33510

Correct answer: 33510

*Explanation: Volume of sphere = 4/3 *(πr*^{3}*) = 4/3 * ( π.20*^{3}* ) = 33510*

The diamter of a sphere having radius 5 is:

- 10
- 25
- 125
- 16

Correct answer: 1. 10

*Explanation: d = 2r = 2 * 5 = 10*

The volume of a right cylinder having radius 2 and height 4 is:

- 6
- 8
- 50
- 101

Correct answer: 3. 50

Explanation: V = πr^{2}h

V = π (2)^{2}4 = 50

The volume of a right circular cone having height 5 and radius 4 is:

- 9
- 251
- 405
- 63955

Correct answer: 2. 251

Explanation: Volume = V = πr^{2}h/3

= π(4*4)^{2}*5/3 = 251

The slant height of a right circular cone having radius 3.5 and height 22 is:

- 484
- 22.3
- 10.8
- 484

Correct answer: 2. 22.3

Explanation: Slant height = √ ( r^{2} + h^{2} )

= √ ( 3.5^{2} + 22^{2} ) = 22.3

Area of base of right circular cone having radius 20 is:

- 63
- 197
- 1257
- 3358

Correct answer: 3. 1257

Explanation: Area of base of right circular cone = *πr*^{2} = *π* * 20 * 20 = 1257

The diagonal of a square whose length of one side is 15:

- 21.2
- 7.5
- 225
- 30

Correct answer: 1. 21.2

Explanation: √ 2 * a

Where a is the length of one side

Diagonal = √ 2 * 15 = 21.2

Excuse for that I interfere … I understand this question. Let’s discuss.
