((I've used 3.14 as pi))

Diameter = circumference / pi
= 4.5 / 3.14
= 1.43

Radius = diameter / 2
= 1.43 / 2
= 0.72

V = pi * r^2 * h
= 3.14 * 0.72^2 * 13
= 21.17
= B

Answer:

x = 249

Step-by-step explanation:

Step 1. Combine like terms

1/3x + 166 = x

Step 2. Subtract 1/3x from both sides

166 = 2/3x

Step 3. Multiply it all by 3/2 to get rid of the 2/3

249 = X

padilas [110]

Well, if Tina can make 3 pies in one hour, she have to do 6 pies and she have already 2 so she can have as many pies as Bella, so the answer is 2 hours

Estimate a 15% tip on a dinner bill of $52.87 by first rounding the bill amount to the nearest ten dollars.

Stels [109]

Answer:

$ 7.9

Step-by-step explanation:

Amount of bill = $52.87 = $52.9

Amount of tip = 15% of $52.9

$= \frac{15}{100} \times 52.9 \\ \\ = 0.15 \times 52.9 \\ = 7.935 \\ = \$ \: 7.9 \\$
