Answer:
The Cylinder with a diameter of 6 cm and height of 2 cm will hold the water
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes.
To describe which figures could hold water we must first calculate their volumes and compare each
the volume of the given cylinder
With diameter = 3cm
Radius = 3/2= 1.5cm
Height = 8cm
Volume of cylinder = πr²h
= 3.142*(1.5)²*8
=7.0695*8
=56.56cm³
Firstly let us calculate the volume of sphere
Given radius r= 2cm
V= 4/3πr³
V= 4/3*3.142*(2)³
V= 100.544/3
V= 33.5cm³
Since the volume is small compared to the cylinder it can't hold the water
Secondly let us calculate the volume of the cylinder
With diameter 6cm
Radius r= 6/2= 3cm
Height 2cm
Volume = πr²h
V= 3.142*3²*2
V= 56.56cm³
Since the volume compared with the cylinder is equal it can hold the water
Answer:
Step-by-step explanation:
A proportion is simply a statement that two ratios are equal. In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
Answer:
A ; 21
Step-by-step explanation:
Here, the side facing the right angle is the hypotenuse and it has a measure of length 42
The side facing the missing angle is the opposite and it has a length of 15
The trigonometric ratio that connects the hypotenuse and the opposite is the sine
The sine of an angle is the ratio of the opposite to the hypotenuse
Thus;
sine ? = 15/42
sine ? = 0.357
? = arc•sim 0.357
? = 21 degrees
