We are asked to solve and determine the total yards that Jules needed to fence his land. Initially, we have an original square lot area of 30 yards by 30 yards. Then it is divided by two and we need to compute for the new perimeter of the land so that we will know the total fence that we need.The solution for the perimeter is shown below:
Perimeter = 30 +15 + 15 + 30 + 15+ 15 + 30 (the middle)
Perimeter = 150 yards
Jules needs 150 yards to fence his land.
Perimeter = 30 +15 + 15 + 30 + 15+ 15 + 30 (the middle)
Perimeter = 150 yards
Jules needs 150 yards to fence his land.
The length of the radius of the cylinder is 2 units.
The lateral surface area of a cylinder = <span>2πrh</span>
where, r = base radius
h = height of cylinder
Now, height of cylinder = 2r units
⇒ 16 π = 2×π×r×<span>h
</span>⇒ 16 π = 2×π×r×2r
⇒
= 4
⇒ r = 2 units
Thus, radius is 2 units.
