Answer:
The volume of the bottle is 46.56cm³
Step-by-step explanation:
Thinking of the bottle as a cylinder we can solve the problem as follows
radius = half of diameter
d = 2.4cm
r = 2.4cm / 2 = 1.2cm
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 10.3cm
π = 3.14
r = radius = 1.2cm
v = (π * r²) * h
we replace with the known values
v = (3.14 * (1.2cm)²) * 10.3cm
v = (3.14 * 1.44cm²) * 10.3cm
v = 4.52cm² * 10.3cm
v = 46.56cm³
The volume of the cylinder is 46.56cm³
Answer:
(2, 0)
(0, -2)
Step-by-step explanation:
A linear function has the form y = Ax + B
where A is the slope, and B is the y intercept
we are told the slope is 1,
y = (1)x + B
now we can plug in the x and y from the known point
2 = 4 + B
B = -2 so the y intercept is (0, -2)
y = x - 2 is the function
The zero occurs when y = 0
0 = x - 2
x = 2 so the zero is (2, 0)
b. a desk 6 feet long 1.5 inches - 0.5 feet
Lets work backwards, he had $5 after it all, and spent $1.25 on a snack, so we add that to the remainder, which is $6.25. then he spent half of that on whatever stuff he likes, so add $6.25 and $6.25, which is $12.50
