The diameter of the whole circle is 2*pi*radius . The arc length is then 80/360*pi*radius*=88*pi
radius=88*180/80
=44*180/40
=22*180/20
=11*180/10
=11*18
=(10+1)*18
=198
The diameter is 2*198=(200-2)=400-4=396

SO BASICALLY THE ANSWER IS 396

Evaluate sin^2 (pi/4) + cos^2(pi/4) + cos.
mart [117]

The answer of sin^2 (pi/4) + cos^2 (pi/4) is √ 2

<u>Step-by-step explanation:</u>

The value of sin^2 (pi/4) = √2/ 2

The value of cos^2 (pi/4) = √2/ 2

=  √2/ 2 +  √2/ 2

=  √2 +  √2 / 2

= 2 √2 / 2

Dividing √2 by 1

= √2
