The green area in the figure above represents a section of grass for a putting green. Find the area of the sector of grass
A A = 32 ft2
B. A = 6 ft2
C. A = 36x ft?
D. A = 72 ft2

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

the best estimate is 3 because   8 can only go into 24 3 times
