Answer:
So, you probably want to get a ruler to make sure there a 10-cm side and a 6-cm side. You will also need a protractor to make an exact 60-degree angle between the sides.
Step-by-step explanation:
It should look something like this.
Note: this parallelogram is not drawn to scale. In other words, this parallelogram does not have the exact angles and side measure. (It just an example)
Answer:
Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit.
Step-by-step explanation:
Given:
The figure of a right triangle ABC.
To find:
The trigonometric ratios
.
Solution:
Using Pythagoras theorem,





Taking square root on both sides.


So, measure of BC is 8 units.
Now,




Similarly,




And,




Therefore, the required trigonometric ration are
.

Answer:
V = 2968.8 cm³ or 2969 cm³
Step-by-step explanation:
Given the radius, r = 7.5 cm, of a cylindrical coffee can whose height, h = 16.8 cm:
We can find the volume of a cylinder by using the following formula:
V = πr²h
Substitute the given values into the formula:
r = 7.5 cm
h = 16.8 cm
V = πr²h
V = π(7.5)²(16.8)
V = π × 56.25 × 16.8
V = 2968.8 cm³ or 2969 cm³
Therefore, the volume of a coffee can is 2969 cm³.
