Answer:

Step-by-step explanation:

area of the sector = 144 π

the whole circle is πr²= 36²π = 1,296π

the whole circle has an angle of 360°

the area of the sector has the angle ∠FAN

∠FAN/360 = 144π/1,296π

∠FAN = 360 * 144π/ 1,296π

∠FAN = 40°

The weight of gemstones, such as diamonds, rubies, and emeralds, is measured in carats. A carat is a unit of measure equal to 20
Alexxx [7]
We are told in the question that 1 carat is equal to 200 mg.

The Hope Diamond is 44.5 carats. Let's multiply the weight of 1 carat by 44.5 to get the weight of the Hope Diamond in mg:

\frac{200mg}{1 carat}* \frac{44.5 carats}{1}=8,900 mg

The total weight of the Hope Diamond is 8,900 mg. However the question asks for the weight in grams. There are 1000 mg in 1 gram, so let's divide the known weight of the Hope Diamond in mg by 1000 to get the weight converted to grams:

\frac{8,900mg}{1000}=8.9grams

Now we know that the weight of the Hope Diamond is equal to 8.9 grams.
