Answer 1

Answer:

$15.7 \:ft$

Step-by-step explanation:

Circumference of a circle is equal to:

$\pi d$

$\pi \times 5$

$=5 \times 3.14$

$=15.7$

Answer 2

Answer:

The circumference of circle is 15.7 feet

Step-by-step explanation:

First, you have to find the radius of circle by dividing the diameter by 2 :

$radius = diameter \div 2$

$radius = 5 \div 2$

$radius = 2.5 \: feet$

Next, you have to substitute it into the formula of circumference, C = 2×π×r where r represents radius :

$C = 2 \times \pi \times 5$

$let \: \pi = 3.14 \\ let \: r = 2.5$

$C = 2 \times 3.14 \times 2.5$

$C = 15.7 \: feet$
