The approximate mass of the spherical weight is 51 pounds

To answer the question, we need to know what the mass of the sphere is

<h3>Mass of the sphere</h3>

The mass of the sphere m = ρV where

  • ρ = density of steel = 0.284 lb/in³ and
  • V = volume of sphere = 4πr³/3 where
  • r = radius of sphere = 3.5 in

So, m = ρV

= ρ4πr³/3

Substituting the values of the variables into the equation, we have

m = ρ4πr³/3

= 0.284 lb/in³ × 4π(3.5 in)³/3

= 0.284 lb/in³ × 4π × 42.875 in³/3

= 48.706π lb/3

= 153.014 lb/3

= 51 lb

The approximate mass of the spherical weight is 51 pounds

I need help with multiplying and dividing powers
Tamiku [17]
You need to know these two formulas:

\huge a^b \times a^c = a^{b+c}\\\\\huge \frac{a^b}{a^c}=a^{b-c}

For example,

5^2 \times 5^3 = 5^{2+3} = 5^5

\frac{2^6}{2^4} = 2^{6-4} = 2^2

In a right triangle, one leg is 20 cm and the hypotenuse is 30 cm. To the nearest hundredth of a cm, find the length of the miss
max2010maxim [7]

Answer:

Step-by-step explanation:

Use Pythagoras’ theorem

square of hypotenuse = sum of squares of two other sides

let the missing side be d

30^2 = 20^2 + d^2

600 = 400 + d^2

d^2 = 200

d = square root of 200

d = 14.142 cm
