New flowers arebeing planted in circular flower bed with 14-foot diameter. If each flower requires 2 squares feet of space, about how many flowers can be planted?
A) 308 flowers
B) 154 flowers
C) 77 flowers
D) 66 flowers

Answer 1

i think its C)77 flowers i hope this helps ;)

Answer 2

the formula is $\pi r {2}$.
So the radius  is half of the diameter.A diameter is across a circle,radius is half a circle so we need to cut 14 in half,thats 7,so you multiply 7*7 it will be 49 so we plug that in $A= \pi (49)$ so the answer will be 153.86 we round that so its 154
