Answer:
The answer to your question is the letter A. 20 ft²
Step-by-step explanation:
Data
length of a side = 10 ft
length of the diameter = 10 ft
length of the radius = 5 ft
Process
1.- Calculate the area of the square
Area of the square = side x side
= 10 x 10
= 100 ft²
2.- Calculate the area of the circle
Area = πr²
Area of the circle = (3.14)(5)²
Area of the circle = 78.5 ft²
3.- Calculate the remaining area
Remaining area = 100 - 78.5
Remaining area = 21.5 ft² ≈ 20 ft²
Step-by-step explanation:
Volume of cylindrical container

Answer:

Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept.
Perpendicular lines:
When two lines are perpendicular, the multiplication of their slopes is -1.
Perpendicular to y=1/8x+2
This line has slope 
So, for the line we want to find the equation, we have that:


So

Find the equation of the line through point (1,−5)
This means that when
. We use this to find b. So:



The equation of the line is:
