Asemicircular flower bed has a diameter of 3 metres. what is the area of the flower bed?

area of a full circle = PI*r^2

r = 3/2 =1.5

using 3.14 for pi

3.14 *1.5^ = 7.065 square meters

 a semicircle is half of a circle so now divide7.065 by2

7.065/2 = 3.5325 square meters, round answer as needed

the correct answer is 5 6 and 7

none.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
