The following measures shown in the diagram with the circle centered at point a ab = 9 mdetermine the approximate major arc length of  .16.63 cm25.38 cm40.39 cm56.55 cm

The approximate major arc length is 16.15m

The formula for calculating the length of an arc

where

Substitute the given the values into the formula:

L = 9(4π/7)

L = 36π/7

L = 16.15 m

Hence the approximate major arc length is 16.15m

AC = 9 m; BC = 16.16 m; BD = 28.27 m; CD = 12.12 m

Find AC

AC = AB = 9 m

Find BC

∠BAC = 2π – 10π/7 = (14π – 10π)/7 = 4π/7

BC = θr = 4π/7 × 9 m = 16.16 m

Find BD

∠BAD = π

BD = θr = π × 9 m = 28.27 m

Find CD

C = 2πr

CD = C – BC – BD = 2πr – 4πr/7 – πr = (14πr – 4πr – 7πr)/7 = (3π/7)r

= (3π/7) ×9 m = 12.12 m

the correct answer is d

hope this

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo
