Ans = Diameter

Choose the best answer:

The diameter of a circle is 50cm then its radius is....

1) 50cm
2) 25cm
3) 35cm
4) 100cm

Answer: 2

SOLUTION 1 :

Given,

d = 50cm

r = $\frac{d}{2}$

r = $\frac{50}{2}$ = 25

r = 25

Choose the correct answer :

The line segment that joins the centre of a circle to any point on the circle is called

1) Chord
2) None
3) Radius
4) Diameter

Answer: 3

SOLUTION 1 :

Ans = Radius

The circumference of a circle whose radius is 14 cm is

1) 88
2) 78
3) 98
4) 83

Answer: 1

SOLUTION 1 :

Circumference of the circle = 2πr

= 2 x $\frac{22}{7}$ x 14²

= 2 x 22 x 2

= 88 cm

Circumference of the circle 88 cm.

The diameter of a circle is 80cm then its radius is....

1) 40cm
2) 80cm
3) 50cm
4) 160cm

Answer: 1

SOLUTION 1 :

Given,

d = 80cm

r = $\frac{d}{2}$

r = $\frac{80}{2}$ = 40

r = 40

Choose the correct answer :

The line segment that joins the centre of a circle to any point on the circle is called

1) Radius
2) Chord
3) Diameter
4) None

Answer: 1

SOLUTION 1 :

Ans = Radius

10)

The circumference of a circle whose radius is 42 cm is

1) 259
2) 264
3) 274
4) 254

Answer: 2

SOLUTION 1 :

Circumference of the circle = 2πr

= 2 x $\frac{22}{7}$ x 42⁶

= 2 x 22 x 6

= 264 cm

Circumference of the circle 264 cm.
