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:

1. 148
2. 706
3. 23.5
4. 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:

1. 28
2. 50265
3. 84
4. 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:

1. 10
2. 25
3. 125
4. 16

Correct answer: 1. 10

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

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

1. 6
2. 8
3. 50
4. 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:

1. 9
2. 251
3. 405
4. 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:

1. 484
2. 22.3
3. 10.8
4. 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:

1. 63
2. 197
3. 1257
4. 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:

1. 21.2
2. 7.5
3. 225
4. 30

Correct answer: 1. 21.2

Explanation: √ 2 * a

Where a is the length of one side

Diagonal = √ 2 * 15 = 21.2
