Answer:
4√2
Step-by-step explanation:
Pythagoras states that:
c² = 4² + 4²
so c² = 2·4²
so c = √(2·4²) = 4√2
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:
Rectangle or parallelogram
The multiplier is 4 (3*4=12, 4*4=16), so 10*4 is 40, therefore the ratio is 10:40
