Question

Can someone please write an expression in terms of x for the area an perimeter of the question (ii)

pictured.
Area of a circle =πr²
Circumference of a Circle= 2πr
π= 3.14

Answer 1

I hope this helps you



ii)


4x=r+r 4x=2r r=2x


Area= pir^2/2+4x. (x-2)


Area=3,14. (2x)^2+4x^2-8x


Area= 3,14.4x^2+4x^2-8x


Area =12,56x^2+4x^2-8x


Area =14,56x^2-8x


Area =x. (14,56x-8)
