Area = r^2 x PI
to find r take the square root of the area:
r = √100 = 10
The circumference of a circle is the diameter times PI.
The diameter is 2 times r = 2 x 10 = 20
The circumference = 20PI m
The answer is C.

Step-by-step explanation:
5w+10=40
5w=40-10
5w=30
w=30/5
w=6
Answer: A) 6

10k+5=65
10k=65-5
10k=60
k=60/10
k=6
Answer: k=6

d=1
Answer: d=1
Answer:
Option 2: y = 6x + -4
Step-by-step explanation:
y = mx + b
y = 6x + -4
Answer: B
Step-by-step explanation:
When you are multiplying exponents, if the base is the same, then you can directly add the exponents together.
We can see that both bases are 6. That means we can add the exponents.
[common denominator]
[add]
Now, we know that the answer will be 
.
Answer:
hello : sin(θ) = 4/25
Step-by-step explanation:
you know : cos²(θ) + sin²(θ) =1 and : cos(θ) = - 3/5
(-3/5)² + sin²(θ) =1
9/25 + sin²(θ) =1
sin²(θ) =1 -9/25
sin²(θ) = 16/25
sin(θ) = 4/25 or sin(θ) = - 4/25
in quadrant 2 : sin(θ) > 0
so : sin(θ) = 4/25
