Answer:

1) The anchor was  released from 72.5 meters above the water's surface.

2)The anchor took 29 seconds to reach the water's surface

Step-by-step explanation:

The rate of drop of anchor = 2.5 meters per second

So, total depth covered by anchor after 45 seconds

= 2.5 meters x 45 seconds

= 112.5 meters

But after 45 minutes, the anchor was 40 meters deep.

So, extra distance traveled by anchor = Total distance covered by anchor - depth of water

= 112.5 meters  - 40 meters  =  72.5 meters

Hence, the anchor was  released from 72.5 meters above the water's surface.

Now, speed of anchor = 2.5 m/sec

So, total time taken to cover extra 72. 5 meters = 72. 5 meters / 2.5 m/sec

= 29 seconds

Hence, the anchor took 29 seconds to reach the water's surface.

Find the area and circumference of the circle below:<br> Diameter - 14 cm
MAVERICK [17]

Answer:

<em>Area : 153.86cm</em>

<em>Circumference:  43.96cm</em>

Step-by-step explanation:

<u><em>To Find:</em></u>

<em>Area __ cm</em>

<em>Circumference__ cm</em>

<u><em>Given:</em></u>

<em>Since, it given that the Diameter is 14 cm</em>

<em>Diameter which is any straight line segment that passes through the center of the circle.</em>

<em>Radius which is half of diameter</em>

<u><em>Note: </em></u>

<em>A = πr  ²                                                          {Area Formula}</em>

<em>C = rd                                                           {Circumference Formula}</em>

<em>pi also known as π = 3.14                            {approximately }</em>

<em>"r " means Radius</em>

<em>"d " means diameter</em>

<em>c = circumference</em>

<em>a = area</em>

<u><em>Solve:</em></u>

<em>A = πr  ²</em>

<em>Since radius is half of the diameter then...</em>

<em>14/2 = 7</em>

<em>Radius = 7</em>

<em>A = 3.14(7)²                                   { (7)² means 7 × 7 </em><u><em>Not </em></u><em>7 × 2 }</em>

<em>A = 3.14(49)                                  { 7 × 7 = 49}</em>

<em>A = 153.86</em>

<em>C = rd       </em>

<em>C = 3.14(14)</em>

<em>C = 43.96</em>

<em>Area : 153.86cm</em>

<em>Circumference:  43.96cm</em>

A rectangular prism has a length of 114 yards, a width of 212 yards, and a height of 4 yards.
drek231 [11]

Answer: 96,672 yards cubed

Step-by-step explanation: The formula for the Volume of a rectangar prism is Length×Width×Height

114yds × 212yds × 4yds = 96,672yds^3

Its already in simplest form since its all yards

But, you can also convert it into miles

In which 1 mile = 1760 yards

So you'd divide 96670 by 1760, and what ever answer youget would be the answer in miles
