Answer:
2nd option
Step-by-step explanation:
using the converse of Pyhagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 100 , then 100² = 10000
60² + 80² = 3600 + 6400 = 10000
then
60² + 80² = 100²
thus the triangle is right
Answer: 3987.8cm³
Step-by-step explanation:
Volume of a cylinder = πr²h
where
π = 3.14
r = diameter / 2 = 10in/2 = 5inches
h = height = 20in
Volume = πr²h
= 3.14 × 5² × 20
= 3.14 × 25 × 20
= 1570inches³
Since 1 inch = 2.54cm
1570 inch = (1570 × 2.54) = 3987.8cm³
Therefore, the volume of the cylinder is
3987.8cm³ cubic centimeters.
Answer:
17/6
Step-by-step explanation:
Answer: See attached.
Step-by-step explanation:
When we have a simple x = a equation, the line will be vertical since all y values of that function/equation are equal to a. In this case, that is 1.
Similar thing for a y = b equation. The line will be horizontal since all x values of that function/equation are equal to b. In this case, that is -5.
