1)What is the exact circumference of a circle with a radius of 15 cm?

The circumference of a circle is calculated by the equation:

C  = 2πr = 2π(15 cm) = 30π cm

2)What is the exact circumference of a circle with a radius of 16?

The circumference of a circle is calculated by the equation:

C  = 2πr = 2π(16 cm) = 32π cm

Answer:

The answer is 30

Step-by-step explanation:

I took the quiz. In order to find the circumference, you will need to multiply your number by 2. In this case, your answer will be 30^^

Solve for x in the equation x/2 = 17. A. x = 34 B. x = 8.5 C. x = 19 D. x = 15

Answers

To "remove" a divided by 2 on one side of the equation, you must multiply it by two, which means you must do it to the other side was well. So you get:

x/2=17
x=(17x2)
x=34

Therefore A is the correct answer.

The line that divides a parabola in half is..?

Answers

The line of symmetry that divides a parabola in half as "The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola".

What is parabola?

A parabola is an approximately U-shaped, mirror-symmetrical plane curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line. Three different parabolas exist. Vertex form, standard form, and intercept form are the three forms. You can access a unique key feature for the graph on each form. A parabola's general equation is written as y = a(x - h)² + k or x = a(y - k)²+ h. Vertex here is indicated by (h, k).
