Question

Circumference of a circle is 220 meters. Find its diameter and area please tell step by step then you will be the brainliest​

Answer 1

Answer:

Hi there!!

here's your answer:

Given:

Circumference = 220 m

To find:

Diameter and area

Solution:

First it is necessary to find radius

Circumference = 2πr

220 = 2× 22/7 × r

220 × 7 / 2 × 22 = r

5 × 7 = r ( After cancellation)

35 = r

Therefore r is 35 m

Diameter = 2r

= 2 × r

=2 × 35

= 70

Therefore Diameter is 70 m

Area = πr^2

= 22/7 × 35 × 35

= 22 × 5 × 35

= 3850 m^2

Hope this helps ☺️

Step-by-step explanation:

Answer 2

Answer:

$circumference = 2\pi \: r \\ 220 = 2 \times \frac{22}{7} \times r \\ \frac{220 \times 7}{2 \times 22 } = r \\ 35 = r \\ therefore \: daimeter = 2 \times r \\ = 70m \\ area = \pi {r }^{2} \\ = \frac{22}{7} \times 35 \times 35 \\ = 3850 {m}^{2}$

hope this helps you
