Step-by-step explanation:

Quadrilateral circumscribing a circle is a quadrangle whose sides are tangent to a circle inside it (see attached diagram).

The area of circumscribed quadrilateral is

$A=p\cdot r,$

where $p=\dfrac{a+b+c+d}{2}$ is semi-perimeter and r is radius of inscribed circle.

In your case, $A=12\ cm^2$

If a quadrilateral is circumscribed over the circle, then the sum of opposite sides is equal, so

$a+c=b+d=10\ cm,$

$P=10+10=20\ cm\\ \\p=\dfrac{20}{2}=10\ cm$

Now

$12=10\cdot r\Rightarrow r=\dfrac{12}{10}=1.2\ cm$

Corbin can shoot 24 baskets In 3 minutes. Which table best represents this relationship?

seraphim [82]

Answer:

Table C

Step-by-step explanation:

This is the proportional relationship:

y = kx

We have x = 3, y = 24, then k is:

24 = 3k
k = 8

The table will look as:

x = 1 ⇒ y = 1*8 = 8
x = 2 ⇒ y = 2*8 = 16
x = 5 ⇒ y = 5*8 = 40

Correct choice is C
