The radius of a circle with an area of 60 square centimeters is represented by the expression √60/π centimeters. What is another

monitta

Answer:

r= 2 √(15/π)

Step-by-step explanation:

Given that :

Area of circle =60sq cm

radius=√60/π

$Area=\pi r^2\\60=\pi r^2\\\\\sqrt{\frac{60}{\pi}}=r\\\\\sqrt{\frac{15\times 4}{\pi}}=r\\2\sqrt{\frac{15}{\pi}}=r$

Hence the radius can be written as 2 √(15/π)

Find positive integers that satisfy

tankabanditka [31]

9514 1404 393

Answer:

(x, y, z) = (1, 2, 3)

Step-by-step explanation:

The equations that result from reduction to row-echelon form are ...

x = 0.4 +0.2t

y = 5.6 -1.2t

z = t

Then t must have a value 5n+3 for 0 ≤ n < 1. That is, t=3.

x = 0.4 +0.2(3) = 1

y = 5.6 -1.2(3) = 2

z = 3

The integers that satisfy are (x, y, z) = (1, 2, 3).
