I am not positive but it looks like it is 16 feet because you subtract from the length of the ladder which gives you 18-2 which equals 16
SOH CAH TOA
This is the acronym for all trigonometric ratios.
Sin. = opposite/hypotenuse
Cos. = adjacent/ hypotenuse
Tan. = opposite/ adjacent.
In this picture the OPPOSITE leg and the HYPOTENUSE is given to us. With this information we can apply the "TOA" ratio.
Sin. R = opposite/hypotenuse
Sin. R = 3/4 or 0.75
Use a calculator or table to find 0.75 in the sin. column.
The final answer should be 49.
Sin. 49 = 0.7547
Answer:
Step-by-step explanation:
Diameter is 7cm
radius is diameter/2 = 7cm/2 = 3.5cm
Answer:
30
Step-by-step explanation:
Answer:
V = 3216.9 
Step-by-step explanation:
Volume of a cylinder = π 
h
We are given diameter, 16cm, and half of it is the radius
r = 8cm
h = 19cm
Substitute the values into the equation
V = π * 
* 19
V = 3216.9
