50 POINTS!!!

Fittoniya [83]

Answer:

18 π cm^2.

Step-by-step explanation:

The area of the whole circle = π r^2 = 81π cm^2.

Since there are 360 degrees in a circle the area of the shaded region =

80/360 * area of the circle.

This = 80/360 * 81 π

= 2/9 * 81 π

= 18 π

A navy cruiser detects a nuclear submarine that is 2500 feet from the cruiser. The angle between the water level and the submari

nataly862011 [7]

Answer:

Depth of the submarine = 668.09 feet

Step-by-step explanation:

From the figure attached,

In triangle ABC,

Distance between a navy cruiser and a nuclear submarine = 2500 feet

Angle between the water level and the submarine = 15.5°

By applying sine rule in the given triangle,

sin(∠BAC)° = $\frac{BC}{AC}$

sin(15.5°) = $\frac{BC}{2500}$

BC = 2500[sin(15.5)]

BC = 668.09 feet

Therefore, submarine is 668.09 feet deep in the sea.

Firlakuza [10]

Answer:

2/3<7/8.

Step-by-step explanation:

Well the easiest and most simple way is to get a common denominator.The lcm of 3 and 8 is 24.so 2*8=16.So 2/3=16/24.Also 7*3 = 21.So 21/24=2/3.so 2/3<7/8.
