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)

How can you find the magnitude of a vector v→=
dalvyx [7]

Answer:

The magnitude of a vector is its <u>length</u>.

To calculate the magnitude of a vector in any number of dimensions, square root the sum of the squares of each dimension.

Therefore, if  \vec v=(x,y)  then its magnitude is:

|v|=\sqrt{x^2+y^2}

Similarly, if  \vec v=(x,y,z)  then its magnitude is:

|v|=\sqrt{x^2+y^2+z^2}
