To measure the length of a school hallway in metric units, you should probaly use meters
You need 20 teaspoons of red paint
Answer:
$355.47 cents.
Step-by-step explanation
since you want to find the square footage of the entire room, hence Home Depot costs $3.40 per square foot, you would clearly need to find the area. Basically find what 8.5 * 12.3 is and then multiply that number by 3.40. Once that is done, put a dollar sign on the answer and BOOM, you got it. :)
so $355.47 cents.
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
