Answer:
I am not sure if this is right but the answer is
The area of a circle with circumference 18π is 254.5
31/7 = 4 3/7.....3/7 is less then 1/2....so the closest integer is 4
Answer:
14
Step-by-step explanation:
its an formula which comes in algebraic expression
Answer:
x=15√2 y=90 degrees.
Step-by-step explanation:
Thanks to the Pythagorean Theorem we know that with any right triangle, A^2+B^2=C^2. In this case we can use 15^2+15^2=sqrt of 450. The square root of 450 is 15 times the square root of 2. Thus x=15√2. Now we need to find y. All angles in a triangle add up to 180 so if we have 45+45+y=180 then y=90.
Expanding
-3h-15+2=4h+24-9
-3h-4h=24-9-2+15
-7h=28
h=4
