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 of the full circle.

Formula

The perimeter of the circle = 2πr

The perimeter of the given shape = (2πr)+r+r =  (2πr)+2r

The area of the circle = πr²

Now,

The perimeter of the given shape =  (2××14)+2×14 =  94 cm

The area of the given shape = (πr²)

= ××14² = 462 sq cm

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

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
