Answer:
The answer is -8
Step-by-step explanation:
First, add 8 to both sides to separate the 3r from the rest of the terms. Now you have 3r = -24. Divide both sides by 3, and now you have r = -8
The perimeter of the rectangle is 50 inches
the perimeter equation in 2 times the length plus 2 times the height (2 x 8 + 2 x 6) which equals 12 + 16= 28, the area is length times width so 8 times 6 which equals 48
48 ft is the area; 28 ft is the perimeter
Answer:1072.3
Step by step:
use the hemisphere formula which is 2/3*pie*r^3
substitute 8 centimeters into the equation.
Answer:
72 inches²
Step-by-step explanation:
Let 
be equal to the width of the rectangle.
Let 
be equal to the length of the rectangle.
Plug in 12 inches as the length
Therefore, the width of the rectangle is 6 inches.
Plug in 12 inches as the length and 6 inches as the width.
Therefore, the area of the rectangle is 72 inches².
I hope this helps!
