Radius is half the diameter, so the radius is 20. The circumference formula is 2 times pi times radius. It simplifies to 40 times pi. The circumference is 125.60in².
Hello there! :}


Question:

The diameter for a circle is 40 in. What is its radius and circumference?


Answer:

1.) To find the radius is d ÷ 1/2 

so , radius = 20 in <<<< answer for radius

2) To find the circumference C = πd
 
= π x 40 

= 125.66 in <<< answer for circumference 



Hoped this helped you solve for your answer!
have a great day =)
