Find the area of the circle that is 9mm

Mathematics
1 answer:
LenaWriter [7]2 years ago

When finding an area of a circle, you need to know radius. The formula of the area of a circle is A=(pi symbol)(r squared). In this case the radius is 4.5mm because you need to divide the total by 2. Multiply 4.5mm and 4.5mm, which is the r squared. Finally multiply your answer to pi and that is the area of the circle.

The sum of the measures of the interior angles in a convex polygon is 1,260°. How many sides does the polygon have?
gavmur [86]
The formula for working out the total interior is:

180(n-2) = 1260

So let’s rearrange by dividing both sides by 180 and find what n is:

n-2 = 7

Then let’s add 2 to both sides to find what n is:

n=9

Each interior angle is 1260/9 = 140°.
The sum of the interior angle and its corresponding exterior angle is 180°.

Therefore, the polygon has 9 sides. :)

What is the equation of the directrix of the parabola given by the equation y2 = -24x?
erma4kov [3.2K]

The equation of the directrix of the parabola given is x = 6, Option D is the correct answer.

<h3>What is Directrix of a Parabola ?</h3>

A parabola is a U shaped curve whose all point are at same distnace from a  point called as focus and a line called as Directrix .

The equation of the parabola given is

y² = -24x

When the standard equation of parabola is

 (y - k)² = 4p (x - h),

where the focus is (h + p, k) and the directrix is x = h - p.

here h = 0

p = -24/4 = -6

x =  0 - (-6)

x = 6

Therefore Option D is the correct answer.
