Answer:
D. 220.16 Square feet
Step-by-step explanation: The shaded area is the space in the square not filled by the circle. So we need to find the area of the circle. The formula for area of a circle is
. So we fill in this equation with the information we already know:

Simplify the exponents
Multiply

So now we know the area of the circle we have to find the area of the square because the circle is inside the square. It is a simple
which is 1,024. Since we are looking for the shaded area we will subtract the area of the circle from the area of the square because the circle is not shaded.
1024-803.94= 220.16 square feet

Answer:
Total number of congruent sections/parts = 7

Step-by-step explanation:
Given that partitions directed segment AB such that AP : PB = 3 : 4, this implies that:
There are 7 parts/congruent sections that AB has been divided into.
Also, point P, partitions AB in the ratio 3:4.
Therefore, there are a total of 7 congruent sections/parts.
Value of k:
Value of k = numerator of the original ratio ÷ sum of numerator and denominator of the original ratio
