Answer: question 5 is C

Question 4 is 37.68

Question 3 is 153.86 ft sq

The question about finding the area with a diameter of 16mm is 803.84

The next one is A. 25÷8

Step-by-step explanation:

C = 2 pi r

C = 2 pi (7.8) and you get 49.01

Becuse the question is asking to round c is the best choice

When using the formula of C = 2 pi r, since radius is half of the diameter, 12÷2=6

The formula for this one is A = pi r sq

You have the radius for this one is 7

Put 7 into that and you get. ~153.94

What is 5/2 divided by 2/5
Len [333]

Answer: 6 and 1/4

Step-by-step explanation: To solve this problem, we first leave 5/2 alone so don't do anything to it.

For our second fraction, we want to switch the numerator and the

denominator which means find the reciprocal of it.

The reciprocal of 2/5 is just the opposite of it when

you flip it and it's going to be 5/2.

Because we did the opposite there, we need to do the opposite

of division and the opposite of division is multiplication.

So now we have 5/2 × 5/2 which is 25/4 or 6 and 1/4.

If one can of paint contains 2 2/5 gallons, how much paint is in one dozen cans of paint?
olasank [31]
Hi there!

Let’s take a look at the question.

One can of paint contains 2 2/5. We can make it easier by transforming the fraction (2 2/5) to a decimal (2.4). Now you have 2.4. Next, it says “one dozen”. One dozen refers to 12 cans. You’ll want to multiply 2.4 with 12.

Your answer is 28.8, or 28 4/5.


Hope this helps!
