PLEASE THIS IS DUE IN 10 MINUTES!!!!!!!!!!!!!!

The diameter of a decorated plate is 20 centimeters. There is a flower painted every 15.7 centimeters around the edge of the plate. How many flowers are painted on the plate? Use 3.14 for π

Answer 1

4 flowers

Explanation:

-Circumference of a circle formula: dπ (diameter times pi)

-So plug 3.14 for π and 20 for the diameter to solve it:

20(3.14) which equals 62.8

-Do 62.8 divided by 15.7 to find how many flowers are around the edge (circumference):

62.8 ÷ 15.7, which equals 4

Answer: 4 flowers

Hope this helped! :)

Answer 2

4

Explanation:

Circumfrence is 2piR or piD, 20x3.14=62.8, 62.8/15.7=4
