Here's a tip Subtracting a fraction is the same as multiplying it's reciprocal so for 3/4 - 3/8 you can do 3/4 x 8/3. Multiplying its reciprocal mean turn the 2nd fraction around
Answer:
9π ft² or approximately 28.26 ft²
Step-by-step explanation:
The area of a circle is A=πr².
Plug 3 in for the radius.
A=π(3²)
A=9π ft²,
or using 3.14 for pi,
Approximately 28.26 ft².
The distance from the top of the mirror to the ceiling once the mirror is hung on the wall is 21 inches
The dimension of the mirror is given as:
From the center of the mirror to the floor of the wall, the distance is:
So, the distance to the top of the mirror will be:
Substitute 24 for height
Convert feet to inches
The distance from the top of the mirror to the ceiling is the difference between the height of the wall and 75 inches.
So, we have:
Convert feet to inches
Hence, the distance is 21 inches

y = 6
Linear: y = 4/-7 x + 4
Standard: (4/7)x + y = 4
