2. calculate the area of each shape respectful
3. add the area of each shape together to get the total surface area of the container
Answer:
Radius: 10 ft
Diameter: 20 ft
Area: 314.15 ft^2
Circumference: 62.83 ft
Step-by-step explanation:
The radius can be found using the diameter. The diameter is 20 feet which is the line that is given in the circle.
The radius(r) is equal to half the diameter(d):
r = d/2 --> r = 20/2 = 10 feet
The area(A) can be found using the radius(r) and pi or 3.14
A = pi(r^2) --> A = pi(10^2) = 314.15 feet^2
The circumference(C) is found by using the radius(r) and pi or 3.14
C = 2pi(r) --> C = 2pi(10) = 62.83 feet
First to get the equation you knew to understand one thing about perpendicular lines. The slope of the line is the opposite reciprocal of the perpendicular lines or the new slope is m = 10.
Then you use the formula
y = mx + b
you plug in your values from the point and the new slope.
(1,5) with new slope m
5= 10(1)+b
5-10=b
-5 = b
then make your new equation
y = 10x -5
that's your line that goes through point (1,5) and is perpendicular to the line given
