Answer 1

Answer:

radius 8.4cm and D56cm

formula of circle,, πr square

22|7(8.4)(8.4)

Answer 2

ANSWER:-

GIVEN

•The radius of circle=8.4cm

•the diameter of circle=56cm

Find:-circumference of circle

so,

$⇒2\pi \: r \\ ⇒2 \times \frac{22}{7} \times 8.4 \\ </p><p> ⇒2 \times 22 \times 1.2 \\ ⇒44 \times 1.2 \\ </p><p> ⇒52.8cm</p><p></p><p></p><p>$

given, that

diameter =56cm

radius=28cm

$⇒2 \times \frac{22}{7} \times 28 \\ ⇒2 \times 22 \times 4 \\ ⇒176cm</p><p></p><p></p><p>$
