Answer:
A. add the areas of both bases to the rectangular area around the cylinder.
Step-by-step explanation:
If we flatten out the cylinder we would have two circles and a rectangle. When you roll up the rectangle, it would make the body of the cylinder. Surface area by definition the total area the surface of an object occupies.
So to get it, we add up the different shapes that make up the cylinder, which is the two circles and the rolled up rectangle.
10%of 710 is 71
now we have 710-71=639
Answer:
64.5°
Step-by-step explanation:
angle of elevation is the angle from the point where the shadow ends. this create a right angle triangle. using tan, you can find the angle.
tan theta = opposite/adjacent
angle = tan^-1(42/20)
angle = 64.5°
1.5 is less then or equal to x which is less then or equal to 14.5
Step-by-step explanation:
1 m = 100 cm So
48 × 100 = 4800 cm
1m = 1000mm
456 mm into m
= 456 ÷ 1000
= 0.456 m
