Use the grid to estimate the area of the circle.
diameter of 3 centimeters
area: about
cm?

Given that the diameter of the circle is 3 centimeters.

We need to determine the area of the circle.

Radius of the circle:

The radius of the circle is given by

Thus, the radius of the circle is 1.5 cm

Area of the circle:

The area of the circle can be determined using the formula,

Substituting and , we get;

Thus, the area of the circle is 7.1 cm²

About 28.27

EXPLANATION:

Formula for area of circle is: πr^2

R= 3, given in the question

3^2 = 9

Answer 9 π = about 28.27

Hope this helped!

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get
