One side of the square below measures 20 cm what is the approximate are of the shaded region of the square

86 I think

Step-by-step explanation:

find the area of circle

A=r^2

A=10^2

A=314

Find the area of square

A= L*W

400=20*20

Subtract

400-314=86

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

a
