Answer:

A = \dfrac{7}{2}\pi~cm^2

Step-by-step explanation:

There is a formula for the area of a sector given the radius and the angle measure.

A = \dfrac{n}{360^\circ}\pi r

n = angle measure

r = radius

A = \dfrac{140^\circ}{360^\circ}\pi \times (3~cm)^2

A = \dfrac{14}{36}\pi \times 9~cm^2

A = \dfrac{7}{18}\pi \times 9~cm^2

A = \dfrac{7}{2}\pi~cm^2
