Find the area and the circumference of a circle with a diameter 8yrd.

nalin [4]

Answer:

Part 1) The area of the circle is $A=50.24\ yd^2$

Part 2) The circumference of the circle is $C=25.12\ yd$

Step-by-step explanation:

step 1

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=8/2=4\ yd$ ---> the radius is half the diameter

$\pi =3.14$

substitute

$A=(3.14)(4)^{2}$

$A=50.24\ yd^2$

step 2

The circumference of a circle is equal to

$C=\pi D$

we have

$D=8\ yd$

$\pi =3.14$

substitute

$C=(3.14)8$

$C=25.12\ yd$
