What is the approximate area of the circle shown below?

D. .

Step-by-step explanation:

We have been given a graph of a circle and we are asked to find the area of our given circle.

We will use area of circle formula to find the area of our given circle.

, where r is radius of the circle.

We can see from our graph that radius of our given circle is 9.4 cm. Upon substituting r=9.4 and in above formula we will get,

Therefore, the approximate area of our circle will be and option D is the correct choice.  

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
