The formula for the area of a circle is A = πr2, where A = area and r = radius.
BaLLatris [955]

The area of a circle with radius of 5 feet is 25π square feet

Step-by-step explanation:

The area of a circle is found out using the formula

A = \pi r^2

Here A is the area

r is the radius of the circle and

pi is a constant

given

Radius = r = 5

We have to find the area in terms of pi

So,

A = \pi r^2\\Putting\ r=5\\A = \pi *(5)^2\\A = 25\pi\ square\ feet

Hence,

The area of a circle with radius of 5 feet is 25π square feet

Keywords: Area, radius

<h2>For x=2</h2>

- 10(2) + y = 4

- 20 + y = 4

y = 24

<h2>For x=1</h2>

- 10( 1) + y = 4

- 10 + y = 4

y = 14

<h2>For x=0</h2>

- 10(0) + y = 4

0 + y = 4

y = 4

<h2>For x=-1</h2>

- 10( - 1) + y = 4

10 + y = 4

y =  - 6

<h2>For x=2</h2>

- 10( - 2) + y = 4

20 + y = 4

y =  - 16
