<u>Image 1 Use:</u>
tan(angle) = opposite/adjacent
<u>Image 2 Use:</u>
cos(angle) = adjacent/hypotenuse

a² + b² = c²
If you're given an angle and 1 side then you can use sin(), cos(), or tan() to solve for the other missing side.
If you're given two sides then you can use the pathagorean theorem, a² + b² = c², to solve for your missing side.
Answer:
5
Step-by-step explanation:
Convert the element to fraction:
/
Switch the division to multipl:
2/1 * 2/5
Cross multiply:
2 is elimiated and 1 and 5 remain.
Answer is 1/5 which is 5.
Recallin that, the diameter is twice as long as the radius, namely the radius is half the diameter, so, if the diameter is doubled, the radius is also doubled.
notice, the new volume is 4 times (πr² h), namely 4 times the original.
