NOTE : PLEASE DO IN FULL STEP & FORMULA ​

Answer 1

Answer:

61.68 cm²

Step-by-step explanation:

The perimeter of a semicircle is r(π+2)

Radius(r) of the semi- circle = 12 cm

• According to the question

= 12 ( 3.14 + 2)

= 12 × 5.14

= 61.68 cm²

Answer 2

Step-by-step explanation:

perimeter of semicircle =

$\pi \: r + diameter$

=3.14×12+24

=37.68+24

=61.68 cm Answer
