Answer 1

The perimeter of the shape is 94 cm and the area is 462 sq cm.

Step-by-step explanation:

Given,

The radius (r) = 14 cm

To find the area and perimeter of the given shape.

The given shape is $\frac{3}{4}$ of the full circle.

Formula

The perimeter of the circle = 2πr

The perimeter of the given shape = $\frac{3}{4}$(2πr)+r+r =  $\frac{3}{4}$(2πr)+2r

The area of the circle = πr²

Now,

The perimeter of the given shape =  $\frac{3}{4}$(2×$\frac{22}{7}$×14)+2×14 =  94 cm

The area of the given shape = $\frac{3}{4}$(πr²)

= $\frac{3}{4}$×$\frac{22}{7}$×14² = 462 sq cm

Answer 2

Answer:

Area = 147pi cm²

Perimeter = (21pi + 28) cm

Step-by-step explanation:

Angle at the centre appear to be 270°

Area = (270/360) × pi × 14²

= 147pi cm²

Perimeter =

[(270/360) × 2 × pi × 14] + 14 + 14

(21pi + 28) cm
