Question

How do you find the area of half a circle with a diamter of 6?

Answer 1

14.13

Step-by-step explanation:

A=1/2
`\pi`
`r^(2)`

substitute
`\pi` for 3.14 and r with 3 because half of diameter is 3.

A=1/2*3.14*
`3^(2)` 3 times 3=9

A=1/2*3.14*9

9 times 3.14 is 28.26

A=1/2*28.26

A=14.13

Answer 2

Step-by-step explanation:

Area of full circle=Πr²

Area of half circle= Πr²/2

Diameter of circle= 6

Radius=r= 3

Area of half circle= Π(3)²/2

= (3.14*9)/2

= 28.26/2

= 14.13
