Step-by-step explanation:
Total amount of paint = 14 gallons
the paint was distributed equally among 4 classes

b.Three classes will use 3× paint of each class
= 
= 10(1/2) gallons
c. 4 student paint 30 square-foot wall the each student would paint
= 7(1/2) square-foot wall.
d. each student will paint

Step-by-step explanation:STEP 1: Draw two straight, intersecting tangent lines onto the circle. The lines can be completely random. However, the process will be easier if you make them roughly square or rectangular.
STEP 2: Translate both of the lines to the other side of the circle. You will end up with four tangent lines forming a parallelogram or a rough rectangle.
STEP 3: Draw the diagonals of the parallelogram. The point where these diagonal lines intersect is the circle's center.
STEP 4: Check the accuracy of the center with a compass. The center should be on target as long as you didn't slip while translating the lines or when drawing the diagonals. Feel free to erase the parallelogram and diagonal lines.
