D) 72 units, you get this answer by adding up 15+15+22+20 units to get the perimeter.
Answer:
~37.70 inches
Step-by-step explanation:
The circumference is π x diameter, so if the diameter is 12, the circumference is π x 12=12π

I think it may be the 2nd one but it’s just a guess… Please don’t take my word on it though!
.75 is the scale factor,
24/32= .75
6/8 = .75
Step-by-step explanation:
•Priya's age = 15 years,
•Amirah's age = (15 + 4) = 19 years
•Shirley's age = (x - 2) = 13 years
Let Priya 's age = x years
Amirah's age = (x + 4) years
Shirley's age = (x - 2) years
✦To find, their respective ages = ?
According to question:
⇒ x+(x+4)+(x-2) = 47
⇒ 3x+2 = 47
⇒ 3x = 47-2 = 45
⇒x = 45/3
⇒ x = 15
∴ Priya's age = 15 years
∴ Amirah's age = (15 + 4) = 19 years
∴ Shirley's age = (x - 2) = 13 years
