What is the circumference of a circle with an area of 50.24cm^2
use 3.14 for pi

3.14*r^2=50.24 => r^2=16. => r=4. => circumference=2*3.14*4=25.12

25.12

Step-by-step explanation:

area of a circle = ||r^2 (|| = pie )

|| r^2 = 50.24

3.14 x r^2 = 50.24

r^2 = 50.24 / 3.14

 = 16

r = 4

circumference = 2 || r

2 x 3.14 x 4

8 x 3.14

25 . 12

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
