Formula: lwh
4*2*6=48m
Answer:
Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.

Step-by-step explanation:
Given A is directly proportional to r² then the equation relating them is
A = kr² ← k is the constant of proportion
To find k use the condition when r = 5, A = 75 , then
75 = k × 5² = 25k ( divide both sides by 25 )
3 = k
A = 3r² ← equation of proportion
(a)
when r = 4, then
A = 3 × 4² = 3 × 16 = 48
(b)
when A = 147 , then
147 = 3r² ( divide both sides by 3 )
49 = r² ( take the square root of both sides )
r =
= 7

How to Calculate Midpoint?
The x-coordinate of the midpoint M of the segment
is the arithmetic mean of the x-coordinates of the endpoints of the segment
. Similarly, the y-coordinate of the midpoint M of the segment
is the arithmetic mean of the y-coordinates of the endpoints of the segment
