The figure in the diagram is composed of a semi-circle and an equilateral triangle. Find the total area of the figure.
A)
43.30 cm2
B)
51.4 cm2
C)
78.54 cm
D
82.57 cm

Area of equilateral triangle is =

Root 3/4*10*10

Root 3/4*100

Root 3*25

25 root 3

Area of semicircle =1/2*22/7*5²

=1/2*22/7*25

(11*25)/7

275/7

=39.28

Adding areas of triangle and semicircle

25 root 3 +39.28

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
