The slope is 9 and the y intercept is 4.
Answer:
17.4 (3 Significant numbers)
Step-by-step explanation:
Formula for finding Cylinder : π r² h
So your 5453 = π x (20cm ÷ 2)² x height
To get height (tallness), divide 5453 by (100π)
Depending on your π, your answer should be either, 17.366 / 17.35 / 17.357 which all rounds up to 17.4 if your question asks for 3 significant figures
If the perimeter of a circle is d*pi, then you would do ((30*3.14)-(20*3.14))/2 to find the perimeter.
30*3.14=94.2
20*3.14=62.8
94.2-62.8=31.4
31.4/2=15.7 cm
