Question

Id love some help!!!

Answer 1

Circle:

circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident.

• 
  `\sf{formula \: to \: find \: the \: area \: is}`

`\large{ \boxed{ \tt{A = {\pi * r}^(2) }}}`

• 
  `\sf{formula \: to \: find \: perimeter \: of \: circle \: is}`

`\large {\boxed{ \tt{p = 2 * \pi * r}}}`

• Continue to Question.

If the radius is 2 inches and

Use 3,14 for π So:

`\tt{ {A = \pi * {r}^(2) }}`

`\tt{A = (3.14 * 2 * 2)}`

`\red{ \boxed{ \bold{A = 12.56 {inches}^(2) }}}`

• So, The Area of circle is 12.56inches²

Answer 2

Answer : 12.56 inches²
Explanation :
Diameter is twice the radius.
Radius = 4 ÷ 2 = 2 inches
Area = 3.14r² = 3.14 × 2² = 12.56 inches²
