Answer:

90.25π

Step-by-step explanation:

The circumference of circle is 2πr, or in other words the diameter times π.

The area of a circle is πr^2.

19π is the circumference of this circle.

So, 19 is the diameter, and 9.5 the radius.

The area if (9.5^2)π.

9.5^2=90.25

So, in terms of π, the area of the circle is 90.25π.

2m-6=4m+8 how do i answer this in algebraic proof
Nonamiya [84]

Answer:

m=-7

Step-by-step explanation:

You begin with the equation:

2m-6=4m+8

The first step of this would be to subtract 2m from both sides. This is the subtraction property of equality.

-6=2m+8

The next step would be to subtract 8 from both sides. This is the subtraction property of equality.

-14=2m

Next, divide both sides by 2. This is the division property of equality.

-7=m

The final step would be the symmetric property of equality.

m=-7

Therefore your proof would have the steps:

subtraction property of equality

subtraction property of equality

division property of equality

symmetric property of equality

The sum of the angles in a triangle = 180°

In an isosceles triangle the base angles are equal, thus

base angle = \frac{180-92}{2} = \frac{88}{2} = 44°
