Question

find the length of tape required to cover the edges of a semi circular disc of radius 10cm​

Answer 1

Step-by-step explanation:

Length of tape required to cover the edges of semicircular disc of radius 10cm=1/2 × 2πr

=1/2 × 2πr

=1/2 × 2 × 3.14 × 10

= 31.4 cm

Hence, Length of tape required to cover the edges of semicircular disc is 31.4 cm

Answer 2

length of tape required to cover the edges of semicircular disc of radius 10cm=1/2 x 2πr

length of tape required to cover the edges of semicircular disc of radius 10cm=1/2 x 2πr1/2 x 2 x 3.14 x 10 = 51.4 cm
