First you have to find the area of the smaller inner circle:
A=πr^2
A=π4^2
A=π16
A= 3.14 x 16
A= 50.24

Then, you have to find the area of the whole circle:
A=πr^2
A=π6^2
A=π36
A= 3.14 x 36
A= 113.04

Now, you simply subtract 50.24 from 113.04 to get 62.8

Use ΔPQR below to answer the question that follows: Which fact is not used to prove that PQR is similar to STR? (5 points) Segme

MissTica

If these are the missing choices:
A) Segments ST and PQ are parallel.
B) Angle P is congruent to itself due to the reflexive property.
C) RP is a transversal line passing ST and PQ.
D) Angles RTS and RQP are congruent due to the Corresponding Angles Postulate.

The fact that is not used to prove that PQR is similar to STR is B) Angle P is congruent to itself due to the reflexive property.

Reflexive property in the given image is on Angle R not angle P.

Which choices are correct when determining the distance between −56 and 69?

Gnesinka [82]

The choices that are correct when determining the distance between −56 and 69 are |-56 - 69| and 125 units

<h3>How to determine the choices that are correct when determining the distance between −56 and 69?</h3>

The endpoints are given as

−56 and 69

The distance between the endpoints is calculated using

Distance = |Difference between endpoints|

So, we have:

Distance = |-56 - 69|

Evaluate

Distance = 125

Hence, the choices that are correct when determining the distance between −56 and 69 are |-56 - 69| and 125 units
