=
Step-by-step explanation:
length of semi-circular circumference + diameter
=theta/360 ×2×pi×r
= 180/360 × 2×3.14×10
=31.4 cm
+
20cm(diameter)
= 51.4 cm

Step-by-step explanation:
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
