If the diameter of a circle is 20 cm, then the radius of the circle is ____.

Detailed Solution: Question 4

  • The diameter of a circle is the distance across the circle through its center.
  • Given diameter: 20 cm
  • The radius is half of the diameter.
  • Formula: Radius = Diameter / 2
  • Calculation: Radius = 20 cm / 2 = 10 cm
  • Therefore, the radius of the circle is 10 cm.
  • The correct answer is: A: 10 cm

Test: Circle- 1 - Question 5

Which segment is the diameter?

Detailed Solution: Question 5

  • A diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle.
  • Hence, BD is the diameter in the image shown.

Test: Circle- 1 - Question 6
Save

If the diameter of a circle is 22 cm, then the radius of the circle is ____.

Detailed Solution: Question 6

  • The correct answer is B: 11 cm.
  • The diameter of a circle is twice the radius.
  • Given: Diameter = 22 cm
  • To find the radius: Divide the diameter by 2.
  • Radius = 22 cm / 2 = 11 cm
  • Therefore, the radius of the circle is 11 cm. 

Test: Circle- 1 - Question 7
Save

If the diameter of a circle is 14 cm, find its radius.

  • 3.5 cm
  • 14 cm
  • 28 cm
  • 7 cm

Detailed Solution: Question 7

The radius of a circle is half its diameter. Here, radius = 14 divided by 2 = 7 cm.

Test: Circle- 1 - Question 8
Save

If the radius of a circle is 5 cm, then the diameter of the circle is ____.

Detailed Solution: Question 8

  • The diameter of a circle is twice the radius.
  • Given radius = 5 cm
  • Diameter = 2 × radius
  • Diameter = 2 × 5 cm = 10 cm
  • Therefore, the correct answer is: A: 10 cm

Test: Circle- 1 - Question 9
Save

Number of circles passing through a given point are ____.

Detailed Solution: Question 9

  • A circle is defined by its center and radius.
  • A given point can be the center or lie on the circumference.
  • For any radius, you can draw a circle passing through that point.
  • Thus, there are infinite possible circles through a single point.

Test: Circle- 1 - Question 10
Save

Find the circumfrence of the circle whose radius, r = 7 cm

Detailed Solution: Question 10

  • Circumference of a circle whose radius is r is given by 2 π r
  • Here r=7 cm 
  • Hence,
  • Circumference of the circle = 2 π (7)
