(C) 113.04mm
(D) 38.31 mm​


plz answer me quickly

Answer 1

Answer:

D. 38.31 mm

Step-by-step explanation:

Circumference of the circle = 2πr

= 2×3.14×6.1

= 38.308

= 38.31 mm

Answer 2

Option D

Step-by-step explanation:

Given:-

Radius of a circle is 6.1 mm

To find:-

Find the circumference of the circle?

Solution:-

Given that

Radius of a circle =r=6.1 mm

We know that

Circumference of a circle = 2πr units

On Substituting the value of r in the above formula

=> C = 2×3.14×6.1 mm

=> C = 38.308 mm

=> C = 38.31 mm ( Correct it to two decimals)

Answer:-

The circumference of the given circle is 38.31 mm

Used formula:-

• Circumference of a circle = 2πr units
• r= radius of a circle
• π=22/7 = 3.14
