I NEED HELP ON QUESTION B AND C ASAP.
ipn [44]

Answer:

  • See below

Step-by-step explanation:

<h3>Part B</h3>

Assumed the dimensions of the top and bottom parts are identical.

Since the cylindrical part has total height of 1.8 cm and the hemisphere volume is transferred to bottom part and the cone part is still full, the value of h is the difference of the total height of cylinder and full part of the top section of cylinder:

  • h = 1.8 cm - 0.3 cm = 1.5 cm
<h3>Part C</h3>

Find the volume of sand in the bottom part. It consists of a hemisphere and a cylinder of 1.5 cm height.

  • V(cylinder) = πr²h = 3.14*(2.6/2)²*1.5 ≈ 7.96 cm³
  • V(hemisphere) = 2/3πr³ = 2/3*3.14*(2.6/2)³ ≈ 4.6 cm³

<u>Total sand in the bottom part:</u>

  • 7.96 + 4.6 = 12.56 cm³

<u>Time taken:</u>

  • 12.56 / 0.05 = 251.2 seconds = 4 min 11.2 seconds

Solve the right triangle. Round decimal answers to the nearest tenth. find the sides and angles
babymother [125]

Answer:

b = 12.6

Step-by-step explanation:

a*2 + b*2 = c*2

6*2 + b*2 = 14*2

36 + b*2 = 196

Subtract 36 from both sides

36 + b*2 = 196

-36             -36

b*2 = 160

Find the square root of both

b = 12.64911064  or 12.6
