Answer:
paper left = 168.56 units²
Step-by-step explanation:
first, figure the area of the square:
area of square = 28x28 = 784 units²
second, figure the area of the circle:
radius = 1/2of 28 = 14
area of circle = Pi x Radius² = (3.14)(14)² = 615.44 units²
subtract area of circle from area of square:
784 - 615.44 = 168.56 units²
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
