I chose D.

A: 72.56 cm^2
B: 80.29 cm^2
C: 60.66 cm^2
D: 70.32 cm^2

Answer 1

D.
`70.34 cm^2`

Explanation:

Area of sector of a circle is given as θ/360*πr²

Where,

r = radius = 12 cm

θ = 56°

Use 3.14 as π

Plug in the values into the formula and solve

`area = (56)/(360)*3.14*12^2`

`area = 70.34`

Area of the sector ABC =
`70.34 cm^2`

The answer is D
