Answer 1

Step-by-step explanation:

We are given,

Radius = 7cm

We have to find : Length of tape required to apply on the boundary

Here the circumference is referred as the boundary

Since,

Circumference = 2πr

Therefore,

The circumference = 2 × π × 7

= 2×22/7 × 7

= 44 cm

And because the protractor is a semi-circle, Therefore the tape required to apply on the boundary = $\boxed{\frac{44}{2} = 22cm}$

Hope it helps❤️
