<h2>Step-by-step explanation:
Convert to simplified fraction:
Convert to a mixed number by placing the numbers to the right of the decimal over 10. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.
Convert to Mixed fraction:
Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there is 1 number to the right of the decimal point, place the decimal number over 10(10). Next, add the whole number to the left of the decimal.
Reduce the fractional part of the mixed number.
Answer:
The surface area of a cone of radius r and height h not equal to one-third the surface area of a cylinder with the same radius and height.
Relationship is
Step-by-step explanation:
Given : The volume of a cone of radius r and height h is one-third the volume of a cylinder with the same radius and height.
To find : Does the surface area of a cone of radius r and height h equal one-third the surface area of a cylinder with the same radius and height?
If not, find the correct relationship. Exclude the bases of the cone and cylinder.
Solution :
Radius of cone and cylinder is 'r'.
Height of cone and cylinder is 'h'.
The volume of cone is
The volume of cylinder is
i.e. volume of cone is one-third of the volume of cylinder.
Now,
Surface area of the cone is
Surface area of the cylinder is
Dividing both the equations,
Which clearly means
i.e. The surface area of a cone of radius r and height h not equal to one-third the surface area of a cylinder with the same radius and height.
The relationship between them is
