Answer:

-

Step-by-step explanation:

Forget using calculators.

Test each point by plugging its coordinates into the equation, and checking if the equation holds true.

Don't bother testing (-3,0), because you can't take the square root of -3.

Craig is constructing weights of different sizes to use in his home gym. One such weight is a solid steel sphere with a radius o
bearhunter [10]

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

prohojiy [21]

Here,

Perimeter (P)=86 feet

Length (l)=25 feet

Let, width(b)= x feet

Then,

Perimeter= 2(l+b)

86=2(25+x)

43=25+x

x=18

Hence, required width is 18 feet...
