Answer:

75.36 cm²

Step-by-step explanation:

SA = 2pi×r×h + 2pi×r²

= 2pi × r × (h + r)

= 2 × 3.14 × 2 × (4 + 2)

= 75.36 cm²

A ship at sea, the Gladstone, spots two other ships, the Norman and the Voyager, and measures the angle between them to be 48°.
ratelena [41]

Answer:

=3501 yards.

Step-by-step explanation:

The three ships form a triangle.  From the Voyager the angle between the Norman and the Gladstone=180-(55+48)=77°

Let the position of the Voyager be V that of Norman be N and that of the Gladstone be G

Then, the distance between Norman and voyager is g

g/sin G=v/ Sin V

4590/Sin 77=g/Sin 48

g=(4590 Sin 48)/Sin 77

=3500.8 yards

The distance between the Norman and the voyager= 3501 yards.

Sara goes on a slingshot ride in an amusement park. She is strapped into a spherical ball that has a radius of 3·10^2 centimeter
kondaur [170]
To solve for the volume of a spherical ball, we use the formula,

                                               V = (4<span>πr^3)/3

The given radius of 3x10^2 centimeters converts to 3 meters. Solving for the volume,
 
                                                V = (4</span>π)x(3^3)/3 = 36<span>π m^3

</span>Thus, Sara is trapped in a spherical ball with a volume of 36<span>π m^3.

X/-3+20=30 help me please
Svetllana [295]

if you're solving for x it's -30

steps: x/-3+20=30

first subtract 20 from both sides then you'll have

x/-3=10 then multiply both sides with -3

you should have x by itself and -30 on the other side

answer x=-30

One angle of an isosceles triangle measures 76º. Which other angles could be in that
GREYUIT [131]

Answer:

52 or 28

Step-by-step explanation:

An isosceles has 2 congruent angles.

There are 2 possibilities:

A) There are two 76-deg angles and one angle of a different measure.

76 + 76 + x = 180

x = 28

B) There are two congruent angles, and 76 is the non-congruent angle.

x + x + 76 = 180

2x = 104

x = 52

Answer: 52 or 28
