A circular hoopla hoop of radius 10cm is cut into 4 equal pieces and re-arranged to make the shape as shown. What is the perimeter of the shape? $ (Take\pi = 3.14)$

The figure below is formed by overlapping a square and a circle. O is the center of the circle. The radicle is 14cm. Find the perimeter of the figure. $(Take \pi= \frac{22}{7})$

The figure below is formed by of 4 identical quarter circles, 1 semicircle and 1 rectangle. Find the area of the shaded figure. Leave your answer in terms of $\pi$.

The figure below is formed by 3 circles with the same center. Their radii is in the ratio 2 : 3 : 4. The diameter of the smallest circle is 4cm. Find the diameter of the smallest circle is 4cm. Find the area of the shaded parts.

The figure below is made up of 2 semicircles with diameters 7cm and 14cm respectively. What is the perimeter of the figure? $(Take \pi = \frac{22}{7})$

The figure below is made up 1 circle, 3 identical rectangles and 12 identical quarter circle of radius 10cm (a) Find the perimeter of the unshaded part, X (b)Find the total area of the shaded parts. $(Take \pi = 3.14)$.

Circumference of Semi: $10 \times 3.142 \times \frac{1}{2} = 15.71$ Circumference of quarter: $15.71 ÷ 2 = 7.855$ Circumference of big quarter: $20 \times 3.142 \times \frac{1}{4} = 15.71$ $15.71 + 7.855 + 7.855 + 15.71 = 47.13cm$

The figure below is made up of one big semi-circle is 4 identical small semi-circles. The diameter of each small semi-circle is 14cm. Find the perimeter of the shaded area of the figure. $(Take \pi = \frac{22}{7})$.
