Hence , Option A is the correct answer.
Answer:
Circumference = 18.84 ft
Area = 28.26 ft squared
Step-by-step explanation:
C(circumference) = 2 x
x r(radius)
radius = 1/2 circumference
1. divide circumference by two to get the radius, which would be three ft.
2. multiply the radius by pie (3.14) and then multiply that by two and you have your circumference, which is 18.84 ft
area =
x r(radius)^2
1. find the radius squared, which would be 9 because 3^2 = 3 x 3 which = 9
2. multiply 9 by pie (3.14) and you get the area which = 28.26
A rhombus area is height times base because has 2 parralell sides and the area of a paralellogram is found by multiplying height by base (aka width)
even though this might not seem wrong, it is correct
so area=height times base
