Answer asap! you! super easy! mrs. davis is planning to put a circular rug in her living room. the circumference of the rug is 31.4 ft. use this information to answer the following questions. use 3.14 for π. c=πd. a = π r^2.

Part A) The diameter of the rug is

Part B) The radius of the rug is

Part C) The area of the rug is

Step-by-step explanation:

Part A) Find the diameter of the rug

we know that

The circumference of a circle (circular rug) is equal to

where

D is the diameter

we have

substitute the values and solve for D

Part B) Find the radius of the rug

we know that

The radius of a circle (circular rug) is half the diameter

we have

substitute

part C) What is the area the rug is covering?

The area of the circle (circular rug) is equal to

we have

substitute

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
