3:2 is equal to 12:8 and 12:8 is not 9:8

Find the area of the circle from the given diameter.

KengaRu [80]

Answer:

B is our answer 12.56

When finding area for circles we do

radius x radius x pi

Since we don't have the radius in the problem we have to figure it out but it wont be so hard knowing that the radius is half of the diameter so 4 ÷ 2 = 2 so 2 is our radius now we need tp square it in easier words multiply by itself so

2 x 2 = 4 then we just do 4 x pi!

So 4 x 3.14 = 12.56 So our answer is 12.56

Hope this helps!

Which one should I choose?

Nastasia [14]

Given:

A figure of a quadrilateral.

To find:

The measures of angle 1 and angle 2.

Solution:

The given figure has two pairs of congruent adjacent sides. So, the quadrilateral in the figure is a kite.

We know that the diagonals of a kit are perpendicular to each other at the point of intersection.

$m\angle 1=90^\circ$

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.

$90^\circ+65^\circ+m\angle 2=180^\circ$

$155^\circ+m\angle 2=180^\circ$

$m\angle 2=180^\circ-155^\circ$

$m\angle 2=25^\circ$

Therefore, the correct option is C.

If a figure is rotated 55 degrees clockwise, what is the counterclockwise rotation?

viktelen [127]

I think it’s 305 because there are 360 degrees about a point so 55 clockwise would be 305 anti-clockwise
