4.What is the area of a circle with a diameter of 5 m?...not urgent

radius=1/2 multiplied by diameter

r=1/2 multiplied by 5

r=2.5

formula=area of circle =pie into r²

22/5 into (2.5)²=area

22/5 multiplied by 6.25=area

22multiplied by 1.25 =area (6.25divided by 5=1.25)

27.5=area of circle

< 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)
