Answer:
5/13
Step-by-step explanation:
Sin = 12/13
cos= 5/13
Tan= 12/5
Surface area of a cylinder = 2 x Pi x r^2 + 2 x Pi x r x h
R = 27 cm
H = 37 cm
Take away the Pi seeing as you want to keep it in terms of Pi
2 x 27^2 + 2 x 27 x 37 = 3456 Pi cm^2
Your answer is B
When using substitution, you want to solve an equation for one variable that doesn’t make the equation worse to work with.
The general idea is that you want to find a variable that has a coefficient of 1 or -1.
In 2.5x - 7y = 7.5, both variables have “bad” coefficients.
In 6.2x - y = 1, the y has a coefficient of -1. That’s where you want to start.
