HELP URGENT. The following sphere has a diameter of 18 cm. What is the volume of the sphere? Use 3.14 for and round your answer
Trava [24]

The volume of the sphere with the given value of diameter is to the nearest tenth is 3052.1cm³.

Option C is the correct answer.

<h3>What is the volume of the sphere?</h3>

The volume of  the sphere is the amount of space occupied within the sphere.

Volume of sphere is expressed as;

V = (4/3)πr³

Where r is the radius and π is pi ( π = 3.14 )

Given that;

  • Diameter of the sphere d = 18cm
  • Radius r = d/2 = 18cm/2 = 9cm
  • Constant pi π = 3.14
  • Volume V = ?

V = (4/3)πr³

V = (4/3) × 3.14 × 9cm)³

V = (4/3) × 3.14 × 729cm³

V = 3052.1cm³

Therefore, the volume of the sphere with the given value of diameter is to the nearest tenth is 3052.1cm³.

Option C is the correct answer.

Find the distance between the two points in simplest radical form. (-5,8) (-8,6)
Tanzania [10]

Answer:

\sqrt{445} cannot be reduced any further, so that's the answer.

Step-by-step explanation:

Use the distance formula:

\sqrt{(x2-x1)^{2} +(y2-y1)^{2}} \\\\\sqrt{(-8-10)^{2}+(6--5)^{2}}\\\\\sqrt{(-18)^{2}+(11)^{2}}\\\\\sqrt{(324)+(121)}\\\\= \sqrt{445}\\

Name the property of real numbers illustrated by the equation 16(3t + 4v) = 48t + 64v.
scZoUnD [109]
The property of real numbers illustrated by the equation 16(3t+4v)=48t+ 64v.

 Therefore, the answer is: Distributive property.

 As you can see, you have the equation 16(3t+4v), and when you apply the Distributive property, you obtain:

 16(3t+4v)
 (16)(3t)+(16)(4v)
 48t+64v
