Question

the circumference of a circular disc is 88m :a - find the radius of the circular disc B- and area of the circular disc ( take paay =22/7
​

Answer 1

Answer:

your ans i

Step-by-step explanation:

$circumference \: of \: circle = 2\pi \: r \\ 88 = \frac{22}{7} \times 2 \times r \\ 2 \times 7 = r \\ r = 14 \\ area \: of \: circle \: = \pi {r}^{2} \\ \frac{22}{7} \times 14 \times 14 = \\ 22 \times 28 = \\ 616 {m}^{2} ans$

Answer 2

Answer:

circumference of circle= 2πr

88m= 2×22/7×r

88×7/44= r

22×7= r

154= r

area of circle= πr²

= 22/7×154×154

= 74536m²
