A circular plate has a circumference of 119.32cm. Calculate the diameter.

Answers

Answer:

Diameter is equal to 38 cm.

Step-by-step explanation:

We know that the circumference equals  πd (where d is the diameter).

If we round the value of π to 3.14 then we will get...

πd = 119.32

(3.14)d = 119.32

d = 119.32 / 3.14

d = 38 cm

Therefore the diameter is equal to 38 cm

1. A bag of 12 oranges costs $2.99. What is the cost per orange?

2. 4 slices of pizza cost $10.50. At this rate, what is the cost of 10 slices of pizza?

3. 4 pieces of candy cost $0.99. At this rate, what is the cost of 7 pieces of candy?

Answers

Answer:

1- $ 0.25.

2- $ 26.25.

3- $ 1.73.

Step-by-step explanation:

1- Given that a bag of 12 oranges costs $ 2.99, to determine what is the cost per orange, the following calculation must be performed:

2.99 / 12 = X

0.249 = X

Thus, the cost of each orange is $ 0.25.

2- Given that 4 slices of pizza cost $ 10.50, to determine what is the cost of 10 slices of pizza at this rate, the following calculation must be performed:

10.5 / 4 x 10 = X

2.625 x 10 = X

26.25 = X

Thus, the cost of 10 slices of pizza is $ 26.25.

3- Given that 4 pieces of candy cost $ 0.99, to determine what is the cost of 7 pieces of candy at this rate, the following calculation must be performed:

0.99 / 4 x 7 = X

0.2475 x 7 = X

1.7325 = X

Thus, the cost of 7 pieces of candy is $ 1.73.
