Question

Calculate the area of each circle and show work

Answer 1

Answer:

$area = 2.54 {ft}^{2}$

Step-by-step explanation:

The formula to find the area of a circle is

$area \: of \: circle \: = \pi {r}^{2}$

Let pi be (3.14), the radios as given in the question is (0.9). Therefore;

$\pi {r}^{2} = \\ (3.14) \: {(0.9)}^{2} \\ 3.14 \times 0.81 = \\ 2.5434 \: or \: 2.54 {ft}^{2}$

                  A circle's radius is 0.9 ft. What is its area?

$\large\blue\textsf{\textbf{\underline{\underline{Answer and How to solve:-}}}}$

Formula for Area of a Circle:-

      $\longrightarrow$ A=πr²

Where

• A = area
• π = pi, 3.14
• r = radius, 0.9 ft; plus it's squared, or multiplied by itself

Substitute the values:-

$\longrightarrow$ A=π(0.9)²

On simplification,

A=0.81π

On further simplification,

A=2.54 ft²

Good luck.
