What is the approximate area of the circle shown?
use 3.143.14 to approximate pipi. round your answer to the nearest hundredth.

Area of circle  is 153.86 cm²

Step-by-step explanation:

Given : Diameter of circle is 14 cm.

We have to find the approximate area of the circle shown.

We know

Area of circle = π·r²

Given diameter = 14 cm

So radius is half of diameter.

So, radius = 7 cm

Thus, Area of circle = π·r²

Area of circle = 3.14 ·7²

Simplify, we have,

Area of circle = 153.86 cm²

Thus, Area of circle is 153.86 cm²

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
