Answer:
Step-by-step explanation:
64×0.5³ = 8 grams
Using the circle theorems, we have proven that m ∠RTW = 15°
<h3>Circle theorems </h3>
From the question, we are to prove that m ∠RTW = 15°
In the given diagram,
measure of arc ST = 30°
∴ m ∠SRT = 30°
m ∠SRT = ∠T + ∠W ( <em>Exterior angle of a triangle equals the sum of the two remote angles</em>)
Also,
∠T = ∠W (<em>Radii of the same circle</em>)
∴ m ∠SRT = ∠T + ∠T
m ∠SRT = 2 × ∠T
30° = 2 × ∠T
∠T = 30° /2
∠T = 15°
∴ m ∠RTW = 15°
Hence, we have proven that m ∠RTW = 15°

The equation to find area is:

A is your area, l is your length, and w is your width. Let's insert the numbers we already have, which are our area and our width.

To solve this, we must divide both 11l and 264 by 11, to get our variable l all alone on one side.
264 / 11 = ?
Solve this, and you'll have your length :)
