The service area of the cylinder is 42
square fts.
<h3>What is cylinder?</h3>
Two parallel bases joined by a curving surface make up the three-dimensional solid known as a cylinder.
Typically, the bases are shaped like circles. The height "h" of the cylinder stands for the perpendicular distance between the bases, while "r" stands for the cylinder's radius.
The uses of cylinder are-
- A popular piece of scientific equipment used to determine the volume of a liquid is a graduated cylinder, sometimes referred to as a measuring cylinder or mixing cylinder.
- Its form is slender and cylindrical. The measured amount of liquid is shown by each marked line on the graduated cylinder.
Total surface area of the cylinder formula:
It is the sum of the base surface area and the lateral surface area;
Total area = base area + lateral area , or
Total area = 2 π r² + (2 π r) h , or
Total area = 2 π r (r + h)
Calculation for the total area of the cylinder;
Base diameter is 6 ft
Radius is 6/2 = 3 ft
Height is 4 ft
Total area = 2
3(3 + 4)
= 6
×7
= 42
Therefore, the total surface area of the cylinder is 42
square fts.

Right angle
Te reason being is that it has a 90° corner.
Hoped this helped
Answer: -2,000,000
Step-by-step explanation:
Think of it as -3,000,000 + 1,000,000
Height is not measured in surface area as that is a 3D look so it is still LW meaning 4 times 1.5 which is 6
Area of cone = 1/3 base × height = 1/3 × 8 × 10 = approximately 26.7 m
Ans= approx. 26.4 m
