If my diameter is 90cm, what is my circumference?

About 282.735cm

Step-by-step explanation:

The formula for circumference is , meaning that the circmference is about 282.735 centimeters. Hope this helps!

C = 90pi cm or approximately 282.6 cm

Step-by-step explanation:

The circumference of a circle is given by

C = pi*d

C = pi *90

C = 90pi

We can approximate pi by 3.14

C = 90*3.14

C =282.6

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
