# Find the area and circumference of the dollar coin

Hint:

### Given the diameter of the circle .Find the radius of circle then Find the circumference of the circle by using the formulas circumference of circle and area of circle = .

## The correct answer is: The circumference of a circle is 9.4247 cm and the area of the circle is 7.0685 sq.cm

### ANS :- The circumference of a circle is 9.4247 cm and the area of the circle is 7.0685 sq.cm.

Explanation :-

Given, the diameter of circle = 2r = 3 cm

Then the radius of circle r = 1.5 cm

Then we get circumference of circle

= 9.4247 cm

The circumference of a circle is 9.4247 cm

Then we get area of circle =

= 7.0685 sq.cm

The area of the circle is 7.0685 sq.cm.

∴The circumference of a circle is 9.4247 cm and the area of the circle is 7.0685 sq.cm.

The circumference of a circle is 9.4247 cm

Then we get area of circle =

The area of the circle is 7.0685 sq.cm.

∴The circumference of a circle is 9.4247 cm and the area of the circle is 7.0685 sq.cm.
