Question

What’s the area and the circumference of a circle with diameter 8m?

Answer 1

50.24

Explanation:

8÷2 is the radius. 3.14×4^2=50.24 m^2

^= where the exponent is supposed to go

Answer 2

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)

`\pink{\boxed{ \sf{Area \: of \: circle = \pi r {}^(2) }}}`

2)

`\pink{\boxed{\sf{Circumference of circle = 2\pi r}}}`

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
