What is the formula for the circumference of a circle using the radius?

1 answer:

4 0

We know that:
C=πd Were π(pi)=3,14... and d=diameter
We know that the radious is 2d, so we aply this to the formula and we get that:
C=2πr

Let her monthly salary be x

1/8x = $65

Answer:

x = 129°

Step-by-step explanation:

∠ ABD and ∠ DBC are a linear pair and sum to 180° , then

y + ∠ DBC = 180°

107° + ∠ DBC = 180° ( subtract 107° from both sides )

∠ DBC = 73°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles , then

x = ∠ DBC + z = 73° + 56° = 129°
