Question

Id love some help!!!

Answer 1

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

Answer 2

Answer:

Circle:

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

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

$\large{ \boxed{ \tt{A = {\pi \times r}^{2} }}}$

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

$\large {\boxed{ \tt{p = 2 \times \pi \times r}}}$

• Continue to Question.

If the radius is 2 inches and

Use 3,14 for π So:

$\tt{ {A = \pi \times {r}^{2} }}$

$\tt{A = (3.14 \times 2 \times 2)}$

$\red{ \boxed{ \bold{A = 12.56 {inches}^{2} }}}$

• So, The Area of circle is 12.56inches²
