If we draw a line from the circle's center to either end of the horizontal line, that line will also be a radius, so it will have length x. This forms a right triangle with side lengths 10 and 19 and hypotenuse x.

Using Pythagorean Theorem:

c² = a² + b²

x² = 10² + 19²

x² = 461

x ≈ 21.5

Answer:

To make 3 kg of water, we need

0.5 kg water

1 kg cement

1.5kg sand

Step-by-step explanation:

Here, we want to calculate the mass of each component needed to make 3 kg of mortar

We work with the ratio

Total ratio is:

1 + 2 + 3 = 6

water

1/6 * 3kg = 0.5 kg

cement

2/6 * 3 kg = 1 kg

sand

3/6 * 3 = 1.5 kg
