Answer:
Using 3.14 for pi
835.24 cm^2
Using the pi button for pi
835.6636459 cm^2
Step-by-step explanation:
The surface area of a cylinder is given by
SA = 2 pi r^2 + 2 pi r h
= 2 * pi ( 7)^2 + 2 pi ( 7) * 12
= 98 pi + 168 pi
=266 pi
Using 3.14 for pi
835.24 cm^2
Using the pi button for pi
835.6636459 cm^2
Answer:
The distance between the two points is approximately 11 units
Step-by-step explanation:
Here, we are to give the distance between the given two points to the nearest whole number;
To calculate the distance, we shall be using the distance formula;
D = √(x2-x1)^2 + (y2-y1)^2
(x1,y1) = (5,6)
(x2,y2) = (1,-4)
D = √(1-5)^2 + (-4-6)^2
D = √((-4)^2 + (-10)^2
D = √(16+100)
D = √(116)
D = 10.77 units which is approximately 11 units
Answer:
