D = 8 ÷ (√2 + 1) ≈ 3.314 units.

Simple something grin grin.. since it's quarter make it half by multiplying it with 2. Then equate it to X, after doing it collect like terms, it will then give you a quadratic equation then solve. shocked


































sad angry wrong place Nairalanders are olodos. We don't know maths, Maths is our enemy even lala sef cannot calculate the Simple interest of adding a snake to his farm every year.

X²= (2r)²+(2r)²
X²= 8r²
X = 2r√2

Also
Let D =Big diameter

Therefore D = X + 2r
8 = 2r√2 + 2r
r = 4/(√2+1)

d = 2r = 8/(√2+1) = 8/2.4142 = 3.314 units to 3 d.p

Area of big circle =πr^2= 3.142*16= 50.272

Area of quadrant =50.272/4= 12.568

Area of inscribed circle = area of big circle -area of quadrant
=50.272-12.568= 37.704

Area of inscribed circle = πd^2/4=37.704

d^2= 48

d=√48
d=6.928 units
