Question

The circumference of a circle is 35.2 metres. Find its diameter and area.
cm?
​

Answer 1

Answer:

hey mate ...

Step-by-step explanation:

diameter of circle = 35.2

so .... d = circumference/value of pi

d= 35.2/3.14

d= 11.21

d = 12

area =C Square/ 4 pi

= 35.2 ×35.2/4x3.14

=98.6

Answer 2

Answer:

Given, circumference = 35.2 metre

2

$2\pi r \: = \: 35.2m \\ 2 \times \frac{22}{7 \: } \times r = 35.2 \\ \frac{44}{7} \times r = 35.2 \\ \frac{44r}{7} = 35.2 \\ 44r \: = 35.2 \times 7 \\ 44r = 246.4 \\ r = 246.4 \div 44 \\ r = 5.6 \\ diameter = 2 \times r \\ 2 \times 5.6 \\ = 11.2 \\ \\ area = \pi {r }^{2} \\ = \frac{22}{7} \times {5.6 }^{2} \\ = \frac{22}{7} \times 31.36 \\ = 22 \times 4.48 \\ = 98.56 {m}^{2}$
