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.

Triangle ABC IS an isosceles triangle AB=BC m

True [87]

Answer:

The measure of angle A is 73°

Step-by-step explanation:

Isosceles Triangles

An isosceles triangle is a triangle with exactly two congruent sides. The angles the congruent sides form with the third side are also equal.

The triangle ABC is isosceles and AB congruent with BC. The angle at B measures 34°.

The other two angles are congruent, i.e. their measures are the same. Since the internal angles of a triangle sum 180°:

$2*m\angle A=180^\circ - 34^\circ =146^\circ$

Thus:

$m\angle A=146^\circ /2=73^\circ$

The measure of angle A is 73°

Answer:

188.

Step-by-step explanation:

We need to find 77% of 244

77% of 244 is the same as 0.77 * 244

0.77 * 244 = 187.88

He can't make a decimal amount, so you would have to round up to nearest whole number

The answer is 188.

Hope this helps :)
