Rudik [331]3 years ago
4 0

Answer:

If the diameter is 18 then the radius r=9 so the area is:

πr2=81π≅254.469

Step-by-step explanation:

Explanation:

The area of a circle is given by the formula πr2 where r is the radius.

What is 17 grams/liters to ounces /quart
Furkat [3]

Answer:

0.57 oz/qt

Step-by-step explanation:

Step 1. Convert <em>grams to ounces </em>

1 oz = 28.35 g

Concentration = 17 × 1/28.35

Concentration = 0.600 oz/L

===============

Step 2. Convert <em>litres to quarts </em>

1 L = 1.057 qt

Concentration = 0.600 × 1/1.057

Concentration = 0.57 oz/qt

17 g/L = 0.57 oz/qt

Question not well presented

Point S is on line segment RT . Given RS = 4x − 10, ST=2x−10, and RT=4x−4, determine the numerical length of RS

Answer:

The numerical length of RS is 22

Step-by-step explanation:

Given that

RS = 4x − 10

ST=2x−10

RT=4x−4

From the question above:

Point S lies on |RT|

So, RT = RS + ST

Substitute values for each in the above equation to solve for x

4x - 4 = 4x - 10 + 2x - 10 --- collect like terms

4x - 4 = 4x + 2x - 10 - 10

4x - 4 = 6x - 20--- collect like terms

6x - 4x = 20 - 4

2x = 16 --- divide through by 2

2x/2 = 16/2

x = 8

Since, RS = 4x − 10

RS = 4*8 - 10

RS = 32 - 10

RS = 22

Hence, the numerical length of RS is calculated as 22
