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 = πr2 = 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 *(πr3) = 4/3 * ( π.203 ) = 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 = πr2h
V = π (2)24 = 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 = πr2h/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 = √ ( r2 + h2 )
= √ ( 3.52 + 222 ) = 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 = πr2 = 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.
