1 answer:

The hypotenuse of a right triangle is equal to the square root of the two sides raised to the second power added together.

This is known as the Pythagorean theorem.

a^2 + b^2 = c^2

It would be helpful to see the actual choices, but let me try to answer anyway:

(1) blue area:

y>=4*x+1

read area

y<-3

(2) blue:

y>3*x-3

red:

y <= 0.5*x + 2

A circle is drawn within a square as shown. What is the best approximation for the area of the shaded region? Use 3.14 to approx

puteri [66]

The answer is around 168.56

work :

the side of the square is 28 in

so the diameter of the circle is 28 in, too(look at the picture)

then the radius is 14 (28/2)

the area of the circle is
$(14 \times 14) \times 3.14 = 615.44$

the area of the square is
${28}^{2} = 784$

so the area of the shaded region will be around:
$784 - 615.44 = 168.56$

good luck
