Here is a general method that you can use to solve all of these:
radius = diameter/2
diameter = radius * 2
circumference = 3.14 * diameter
area = 3.14 * radius * radius
Answer:
False

The ratios that can be used are some, cosine, tangent, etc.
Answer:
2nd option
Step-by-step explanation:
- 5 = ← in the form
The value of c is 5 units.
Step-by-step explanation:
Given,
WY = a = 4
ZY = b = 3
As WYZ is forming a right angle triangle, therefore, we can use pythagorean theorem to find the value of c
Taking square root on both sides
The value of c is 5 units.

Answer:
-x-9
Step-by-step explanation:
-(x+9)
The "-" at the beginning can be rewritten as -1
=-1(x+9)
To distribute -1 into the parentheses, multiply each value inside by -1
=(-1)(x)+(-1)(9)
=(-x)+(-9)
= -x-9
