A bead is formed by drilling a cylindrical hole of 2mm diameter through a sphere with an 8mm diameter. Estimate the volume of th

e bead to the nearest whole?

Volume of the bead = Volume of the sphere - volume of the cylindrical hole = 242.95 mm³.

<h3>What is the Volume of a Sphere and a Cylinder?</h3>
  • Volume of a sphere = 4/3πr³
  • Volume of a cylinder = πr²h

Volume of the bead = Volume of the sphere - volume of the cylindrical hole

= 4/3π(4³) - π(1²)(8)

= 268.08 - 25.13

Volume of the bead = 242.95 mm³

Answer:

V =113.04

Step-by-step explanation:

A sphere has a surface area of 113.04

SA = 4 pi r^2

113.04 = 4 pi r^2

Let pi 3.14

113.04 = 4 *(3.14) r^2

113.04 = 12.56 r^2

Divide each side by 12.56

113.04/12.56 = r^2

9 = r^2

Take the square root of each side

3 =r

We want to find the volume

V = 4/3 pi r^3

V = 4/3 (3.14) 3^3

V =113.04

Which expressions are equivalent to -3(2+7) A: -6+21 or B:-21+6​
Neporo4naja [7]

<u>Answer:</u>

None

<u>Explanation:</u>

Can u help me to answer 1-4? Please and thankyou

1. ) 1 thru 9 are both natural numbers and whole numbers. 0 is a whole number, but not a natural number.

2.) 6...it is a natural number because it is a counting number and it is whole, it is a whole number and it is an integer as well. It is also rational because it can be turned into a fraction 6/1.

3.) -2 is a rational number because it can be turned into a fraction -2/1, but it is not a whole number because it contains a negative.

4.) That number would be 0
