PLEASE HELP ASAP!! The diameter of each of the three circular lights in a traffic signal is 7 inches. In this activity, you will find the total area of the three lights.

Part A
Each circular light has a diameter of 7 inches. What is the radius of each light?

The radius of the circle is 3.5 inches.

Step-by-step explanation:

The radius is half the diameter:R= 1/2 d

Substitute the value of d (7 inches) in the formula to find r:

r= 1/2 x 7 in

r= 3.5 in

3.5 inches should be the answer.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and
