Question : -
Find the area and the circumference of a circle with diameter 8 m .
Given : -
- Diameter of circle = 8 m
To Find : -
- Area of circle
- Circumference of circle
Formula Used :
1)
[tex] \pink{\boxed{ \sf{Area \: of \: circle = \pi r {}^{2} }}}[/tex]
2)
[tex] \pink{\boxed{\sf{Circumference of circle = 2\pi r}}}[/tex]
So Starting Our Solution :
We know that radius of circle is always halves of its diameter . So radius of circle :
- 8/2
- 4 m
1) Finding area :
- πr²
- 3.14 × 4 × 4
- 3.14 × 16
- 50.24 m²
Therefore, area of circle is 50.24 m² .
2) Finding circumference :
- 2πr
- 2 × 3.14 × 4
- 6.28 × 4
- 25.12 m
Therefore, circumference of circle is 25.02 m
