Find the area of this circle. A= ?
5 in
Hint: First, plug in the value
of the radius into the
formula for r.

All you need to do, is just plug in 5 into the 'r' which represents the radius.

So;

A = πr^2

A = 3.14 x 5^2

A = 3.14 x 25

A = 78.5

78.5

Step-by-step explanation:

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
