Ok so the radius is half the diameter, and the diameter is half the circle. And the area is the space inside a circle. And pie is 3.14.
So if your radius is 10 then you will multiply 10 x 10 to get 100. Then multiply 100 x pie or 3.14 which you will get, 314cm². So your answer is 314cm²
The formula for an area of a circle is radius x radius = ?
Then multiply pie, 3.14 by your new radius x radius, and you got your answer.
Answer:
c=-25
Step-by-step explanation:
-3(-c-18)=-3-18
3c+54=-21
3c=-21-54
3c=-75
c=- 75/3
=-25
If this is just normal division, the answer is 409.
Answer:
y = 2x + -5
Step-by-step explanation:
If you look at the graph, you can find that the slope is 2/1 which is simply just a slope of 2. The y-intercept can be found x = 0, so plug in 0 for x, solve from there and you get -5 for the y-intercept.
