Question

Please help ASAP! Randy is putting bricks around the outside of his flower bed to protect the plants. A; If the diameter of his flower bed is 100 inches, what is the distance around the garden? B; If the curved bricks he wants to buy are each half a foot long, how many will he need to put around the outside of the garden? Explain. Thank you!!!

Answer 1

You need the circumfrence of the flower bed.  
C=diameter x pi.  

C=100in.x pi. pi=3.1415.....  

C= 100 x 3.1415

C=314.15 which is the distance in inches around the flower bed.

Each curved brick is half a foot long, which is 6 inches.  

314.15 divided by 6

= 52.358 bricks.
