Polygon ABCDEF is a regular hexagon. Find the perimeter of the polygon. Round to the nearest hundredth. Round to give final answer only.

Answers

Answer:

  12√2 ≈ 16.97

Step-by-step explanation:

Points A and B are on grid lines. The difference B-A is (2, 2), so the distance formula will tell you the length of that segment is ...

  √(2²+2²) = 2√2

The regular hexagon has 6 sides all the same length. The perimeter is the sum of those lengths, so is ...

  6 × 2√2 = 12√2 ≈ 16.97 . . . . units

A sphere has a radius of 6 meters. A second sphere has a radius of 3 meters. What is the difference of the volumes of the spheres?

Answers

Answer:

791. 28 m^3\n

Step-by-step explanation:

Volume of sphere with 6 meter radius

= (4)/(3) \pi r^3\n= (4)/(3) (3.14) ( 6^3)\n= 904.32 m^3\n

Volume of sphere with 3 meter radius

= (4)/(3) \pi r^3\n= (4)/(3) (3.14) ( 3^3)\n= 113.04 m^3\n

Difference between the volume of two sphere

= (904 .32 m^3)- ( 113.04 m^3)\n= 791.28 m^3\n

∆volume = 4/3 *pi * (R^3 -r^3 )
= 4/3 *pi*((6)^3 -(3)^3)
= 252*pi
= 791.68 m^3

Martina hits a volleyball ball upward with an initial velocity of 13 meters/sec. When she hits the ball, it is one meter above the ground. How long will it take the ball to hit the ground?

Answers

the ball will take 6.5 seconds to hit the ground



Final answer:

The question from the student is about time airborne for a volleyball hit upwards with an initial velocity. A physics equation of motion is utilized to solve it by inserting the values and extracting time.

Explanation:

The subject of the question is physics, specifically the subtopic of kinematics in terms of upward motion. The problem can be solved by using the equation of motion: `y = y0 + v0 * t - 0.5 * g * t²`, where y0 is the initial height, v0 is initial velocity, g is the acceleration due to gravity and t is the time taken. In this situation:

  • y0 is 1 meter (the starting height of the ball).
  • v0 is 13 m/s (the initial upward velocity of the ball).
  • g is approximately 9.8 m/s² (the acceleration due to gravity).

Set y (the final position) to 0 (ground level), and solve for t (time taken):

0 = 1m + (13 m/s) * t - 0.5 * (9.8 m/s²) * t²

Solving this quadratic equation, we get two solutions as the time cannot be negative for this context, so choose the positive value as the time taken for the ball to hit the ground. This will give the duration the volleyball remains in the air after being hit by Martina.
