Find the circumference and the area of a circle with diameter equal to 8.6 inches. Use 3.14 for pi

mariarad [96]

Answer: Circumference of circle = 27.004 inches

Area of circle = 58.0586 inches²

Step-by-step explanation:

Diameter of circle = 8.6 inches

Pi ( $\pi$ ) = 3.14

Circumference of circle (With diameter) = $\pi \\$ d ( $\pi$ ×diameter)

= 3.14 × 8.6

= 27.004 inches

Area of circle (With diameter) = $\pi$ $d^{2}$ /4

= 3.14 × 8.6 × 8.6 / 4

= 3.14 × 73.96 / 4

= 58.0586 inches²

Matt measures a subway token and calculates that it has an area of 254.34 square millimeters. What is the token's circumference?

aivan3 [116]

Answer:

The token's circumference is $56.52\ mm$

Step-by-step explanation:

step 1

Find the token's radius

The area of the circle is equal to

$A=\pi r^{2}$

we have

$A=254.34\ mm^{2}$

$254.34=(3.14)r^{2}$

$r^{2}=254.34/(3.14)$

$r^{2}=81$

$r=9\ mm$

step 2

Find the token's circumference

The circumference of the circle is equal to

$C=2\pi r$

we have

$r=9\ mm$

substitute

$C=2(3.14)(9)=56.52\ mm$
