Answer:
3. 43.96 cm
4. 81.64 ft
Step-by-step explanation:
3. The formula for the circumference of a circle in terms of radius is ...
C = 2πr
When π is approximated by 3.14, this becomes ...
C ≈ 6.28r
The only answer choice even close to 6.28×(7 cm) is the one shown above.
___
4. The formula for the circumference of a circle in terms of diameter is ...
C = πd
When π is approximated by 3.14, this becomes ...
C ≈ 3.14d
The only answer choice anywhere close to 3.14×(26 ft) is the one shown above.
_____
<em>Comment on the solution</em>
For questions like these, you only need to be able to estimate the answer to 1 or 2 significant digits. The answer choices are not so close together as to cause any confusion.
6×7 = 42, so the answer will be a few more than 42.
3×26 = 78, so the answer will be within a few numbers larger than that.
In each case, the answer is the largest value on the list. The other choices differ by a factor of 2, so aren't even close.
First lets convert the pints to cups.
1 pint = 2 cups
12 pints = ? cups
Now lets multiply to find out how many cups are in 12 pints.
12 × 2 = 24
24 cups in 12 pints.
Now lets look at the information we have.
4 cups of water per 9 servings
Now lets divide to see how many time 24 goes into 4.
24 ÷ 4 = 6
Now lets multiply:-
6 × 9 = 54
So, 54 servings of water fir in 12 pints of water.

Step-by-step explanation:
Answer: 6x + 15
Step-by-step explanation: The distributive property tells us that if we are given an expression such as 3(2x + 5), we can multiply the 3 by both the 2x and the 5 to get 6x + 15.
