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
