Question

Circle assignment! THANKS so much its worth so much of my grade

Answer 1

1. B) Figure B.

2. C) Figure C.

3. D) Figure D.

4. C) Figure C.

Explanation:

Given: Radius of Circle A= 4

Radius of Circle B= 5

Radius of circle C= 6

Radius of circle D= 7

Now, finding circumference and area of all the circle.

We know, circumference of circle=
`2\pi r`

Area of circle=
`\pi r^(2)`

Where, r= radius of circle and π = 3.14

First, solving for figure A

Circumference=
`2* 3.14* 4= 25.12\ cm`

Area=
`3.14* 4^(2) = 50.24\ cm^(2)`

Solving for Figure B

Circumference=
`2* 3.14* 6= 31.4\ cm`

Area=
`3.14* 5^(2) = 78.5\ cm^(2)`

Solving for Figure C

Circumference=
`2* 3.14* 6= 37.68\ cm`

Area=
`3.14* 6^(2) = 113.04\ cm^(2)`

Solving for Figure D

Circumference=
`2* 3.14* 7= 43.96\ cm`

Area=
`3.14* 7^(2) = 153.86\ cm^(2)`

∴ 1. Answer is Figure B.

2. Answer is figure C.

3. Answer is Figure D

4. Answer is Figure C.
