Gold in the form of solid cylinders will be molded into solid blocks. Each cylinder has a diameter of 6.19 cm and a height of 6

cm. Each solid block will have a volume of 360 cm3. How many cylinders of gold will it take to mold one block of gold?

Most of the information's required for solving the question is already given.
Height of each cylinder (H) = 6 cm
Diameter of each cylinder (D) = 6.19 cm
Then
Volume of each cylinder = <span>πD²H / 4
                                       = [3.14 * (6.19)^2 * 6] / 4
                                       = [3.14 * 38.32 * 6] / 4
                                       = 721.88/4
                                       = 180.47 cubic centimeter
Volume of each solid block of gold = 360 cm^3
Then
Number of cylinders required = 360/180.47
                                               = 1.99
                                               = 2
From the above deduction, we can conclude that 2 cylinders will be required.</span>

First, solve for the volume (V) of each cylinder by the equation,
                                     V = πd²h / 4
where d and h are diameter and height, respectively. Substituting the given values,
                                     V = π(6.19 cm)² x (6 cm) / 4 = 180.56 cm³
To determine the number of cylinders needed, divide the volume of the solid block by the volume of the cylinder,
                                       n = 360 cm³ / 180.56 cm³ = 1.99
Thus, approximately 2 cylinders are needed to mold one block of gold.

Answer:

First Image:         Option D

Second Image:   Option D

Third Image:       Option C

Fourth Image:     Option B

Fifth Image:         Option B

Step-by-step explanation:

<u>First Image:</u>

  • Supplementary angles is two angles whose sum is 180 degrees (straight line)
  • 180 - 47 = 133°
  • ? is an obtuse angle is any angle greater than 90° which checks the answer

<u>Second Image:</u>

  • A triangle angles adds up to 180°
  • Two angles are already given
  • 72 + 45 + ? = 180° → 117 + ? = 180° → ? = 63°
  • ? is an acute angle is an angle that measures between 90° and 0°

<u>Third Image:</u>

  • Supplementary angles is two angles whose sum is 180 degrees (straight line)
  • 180 - 110 = 70°
  • ? is an acute angle is an angle that measures between 90° and 0°

<u>Fourth Image:</u>

  • Supplementary angles is two angles whose sum is 180 degrees (straight line)
  • 180 - 120 = 60°
  • we are shown a right angle which = 90°
  • A triangle adds up to 180°
  • 180 - 90 - 60 = 30
  • ? = 30°
  • ? is an acute angle is an angle that measures between 90° and 0°

<u>Fifth Image:</u>

  • Supplementary angles is two angles whose sum is 180 degrees (straight line)
  • 180 - 85 = 95°
  • ? is an obtuse angle is any angle greater than 90° which checks the answer
