If a circle has a radius of 13 and a sector defined by a 7.4 degree arc, what is the area, in cm2, of the sector? round your answer to the nearest tenth.

For this case the area of the sector is given by:

A = (S ' / S) * (pi) * (r ^ 2)

Where,

S ' / S = relation of arcs

r: radius of the circle

Substituting values we have:

A = (7.4/360) * (3.14) * (13 ^ 2)

A = 10.9080111

Rounding off we have:

A = 10.9 cm^2

Answer:

the area of sector is:

A = 10.9 cm^2
