Acircle with a radius of 3cm sits inside a 8cm x7cm rectangle. what is the area of the shaded region?

27.73 square centimeters

Step-by-step explanation:

Assume the shaded region is the area outside the circle but inside the rectangle.

Now, we need to find the area of rectangle and area of circle. Then we will subtract area of circle from area of rectangle to get our desired answer.

Area of Rectangle = length * width

Area of Rectangle = 8 * 7 = 56

Area of circle is given by the formula:

Area =  

Where r is the radius, which is 3

So,

Area of Circle =

Thus, area of the shaded region is:

Area of Shaded Region = 56 - 28.27 = 27.73 square centimeters

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
