1) what is the area of a sector with a central angle of 5π/7 radians and a diameter of 5.6 in.? use 3.14 for π and round your final answer to the nearest hundredth. enter your answer as a decimal in the box. 2) what is the area of a sector with a central angle of 4π/5 radians and a radius of 11 cm? use 3.14 for π and round your final answer to the nearest hundredth. enter your answer as a decimal in the box.

1.

the area of a sector to the nearest hundredths is,

2.

the area of a sector to the nearest hundredths is,

Step-by-step explanation:

Area of a sector(A) is given by:

         .....[1]

where,

r is the radius and

is the angle in radian.

(1)

As per the statement:

a central angle of 5π/7 radians and a diameter of 5.6 in

⇒

We know that:

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

⇒

⇒

or

r = 2.8 in.

Substitute these in [1] we have;

use 3.14 for π

⇒

Simplify:

⇒ square inches

therefore, the area of a sector to the nearest hundredths is,

Similarly:

2.

a central angle of 4π/5 radians and a radius of 11 cm

⇒

Substitute these in [1] we have;

use 3.14 for π

⇒

Simplify:

⇒ square inches

therefore, the area of a sector to the nearest hundredths is,

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
