Answer:1384.74 square inches
Step-by-step explanation:
Diameter=42 inches
Radius=42/2
Radius=21 inches
π=3.14
area of circle=π x radius x radius
Area of circle=3.14 x 21 x 21
Area of circle=1384.74 square inches

Answer:
A really out of focus picture, but I think this might be what you want.
Step-by-step explanation:
A line is perpendiculat to another which has a slope of m if the perpendicular line has a slope of -1/m.
That means that if the product of slopes of two lines is -1, the two lines are perpendicular.
Here, y1=-7/4x, or m=-7/4
The perpendicular should have a slope of -1/m=-1/(-7/4)=4/7
