Answer:
A= 695.3cm²
Step-by-step explanation:
- We khow that the area of anctagon is : A= 2(1+)*a² with a the side
- so A= 2(1+√2)*a² = 695.29= 695.3 cm²
Answer:
28.3 square meters.
Step-by-step explanation:
So we know that the radius of the circle is 3 meters. With that, we can figure out the area of the circle.
The area of a circle is given by the formula:
Plug in 3 for r:
Square the number:
Use a calculator. Approximate:
Therefore, the area of the circle is approximately 28.3 square meters.
Answer:
slope = - 3 y-intercept = 36
Step-by-step explanation:
12x + 4y = 144 , will allow this to be done.
so 4y = - 12x + 144
now dividing both sides of the equation by 4 will give
y = - 3x + 36 , which is now in the required form
slope = - 3 and y-intercept = 36
Answer:
it exactly 0,5 which is 50% which means 5 out of 10 timea
You have not included any choices, but 2 to the power of -four is equal to 1/16
