What is the approximate area of the shaded sector in the circle shown below? correct answer only 100

The area of 1/2 a circle formula:

A = (πr²)/2

diameter = 5.4
radius = d/2 
radius = 5.4/2
radius = 2.7

plug in 2.7 for r

A = π(2.7)²/2

Simplify

A = π(7.29)/2

Remember that π = 3.14

3.14(7.29) = 22.89 (rounded)

22.89/2 = 11.45 (rounded)

A) 11.45 cm² is your answer

hope this helps

than do 23.50 times 18 and then divide your answer by 100 than you will get x.

Xis equal to three
