<h2>circumference = 50.24cm</h2><h2>area = 200.96cm²</h2>
Step-by-step explanation:
radius (r) = 8cm
circumference = 2π×r
= 2 × 3.14 × 8
= 50.24cm
area = π × r²
= 3.14 × 8 × 8
= 200.96cm²

Answer: A=448+196pi, P=60+14pi
Step-by-step explanation:
I'm assuming that the figures which appear to be semicircles are semicircles and that the quadrilateral is a rectangle.
The perimeter is 16 + 16 + 28 + (28/2)(pi)= 60+14pi
area is area of rectangle + area of semicircle
= (16)(28)+(pi)(14)(14)=448+196pi
