What is the area of a sector with a central angle of 3π/5 radians and a diameter of 21.2 cm? use 3.14 for π and round your final answer to the nearest hundredth. enter your answer as a decimal in the box.

the area of a sector to the nearest hundredths is, 105.84 cm^2

Step-by-step explanation:

Area of a sector(A) is given by:

         .....[1]

where,

r is the radius and

is the angle in radian.

As per the statement:

a central angle of 3π/5 radians and a diameter of 21.2 cm

⇒

We know that:

Diameter(d) = 2(radius(r))

⇒

⇒

or

r = 10.6 cm

Substitute these in [1] we have;

use 3.14 for π

⇒

Simplify:

⇒ square cm

therefore, the area of a sector to the nearest hundredths is, 105.84 cm^2
