SERIOUS ANSWERS ONLY

12.56 sq. inches

Step-by-step explanation:

First, the formula is π r²

half of 4 is 2, and now we have our radius

so 3.14 · 2² = area

3.14 · 4 = area

12.56 = area

Your answer is 12.56 sq. inches

The answer is 12.6 sq inches

Tbh, i came up with 12.57 sq inches but it wasnt an option . Give pls :3 :)

Please dont report but i got it off the internet, i just typed in google, what is the area of a circle with the diameter of 4. You should do it so you wouldnt take away points :)

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

da freeck kinda math is this just drop out
