Answer:

(1-sinA-cosA)^2 = 2(1-sinA)(1-cosA)\\Solution,\\L.H.S. = (1-sinA-cosA)^2 = [(1-sinA)-cosA]^2\\~~~~~~~~~~=(1-sinA)^2-2cosA(1-sinA)+cos^2A\\~~~~~~~~~~=1-2sinA+sin^2A-2cosA(1-sinA)+cos^2A\\~~~~~~~~~~=1-2sinA+sin^2A+cos^2A-2cosA(1-sinA)\\~~~~~~~~~~=1-2sinA+1-2cosA(1-sinA)\\~~~~~~~~~~=2-2sinA-2cosA(1-sinA)\\~~~~~~~~~~=2(1-sinA)-2cosA(1-sinA)\\~~~~~~~~~~=(1-sinA)(2-2cosA)= 2(1-sinA)(1-cosA)

The area of a circle is 81 ft 2 . What is the π circumference? Leave in terms of Pi.
KonstantinChe [14]

Answer:

10.2π

Step-by-step explanation:

Given data

Area of circle=  81 ft^2

Also, the expression for the area of a circle is

A=πr^2

substitute

81=3.142*r^2

r^2= 81/3.142

r^2= 25.77

square both sides

r= √25.77

r= 5.1

Also, the expression for the circumference is

C= 2πr

substitute

C= 2*π*5.1

C= 10.2π

Hence the circumference is 10.2π
