Answer is choice B: the circumference of a circle is the same as perimeter and is defined by πd (or pi times diameter) We can cut this in half because we are working with a semicircle: so we have 6π which approximates to the value in answer
when using 3.14 for pi
Woops: forgot to add the diameter of 12 so we would have 30.84
Okay so basically an integer is just a whole number that isn’t a fraction. Comparing integers is basically comparing whole numbers. For example, comparing the numbers 2 and 34 would be 2<34 and that’s comparing them to each other! :)
To the nearest inch it'll be
d×3.14=63
= 20 inches
Answer:
A. 12n - 6
Step-by-step explanation:
12 times a number which is n so
12n then minus 6 ,
12n-6
hope this helps
