Answer 1

Answer:

1. RP is a chord in this figure.

And minor arc is RP going from the circumference of the circle.

Second question's answer :

$volume \: of \: cuboid \: = l \times b \times h \\ 7cm \times 2cm \times x = 42 {cm}^{3} \\ 14 {cm}^{2} \times x = 42 {cm}^{3} \\ x = \frac{42 {cm}^{3} }{14 {cm}^{2} } \\ x = 3cm$

Please mark my answer as the brainliest answer.

Hope it helps you.
