Find the circumference and the area Of the circle with diameter 4yd Use vale 3.14 to help with answerBe specific with answers with right symbol Yd , Yd2 or Yd3

Answer:circumference: 12.56 ydarea: 12.56 yd²Step-by-step explanation:The formula for circumference is ...   C = πd   C = (3.14)(4 yd) = 12.56 yd . . . . . . . . fill in the numbers; do the arithmeticThe circumference is 12.56 yd.__Since the diameter is 4 yd, the radius is half that, or 2 yd. The formula for the area is ...   A = πr²Fill in the numbers and do the arithmetic.   A = (3.14)(2 yd)² = 12.56 yd²The area is 12.56 yd²._____Comment on unitsIn problems such as these, I find it is often useful to keep the units with the numbers. The units can be treated like any variable: multiplied, divided, measures combined by addition or subtraction of "like units".Just as (2a)² = 2²·a² = 4a², so does (2 yd)² = 2²·yd² = 4 yd². You can be sure that if the units of the problem don't make sense, there is an error somewhere.
