Answer:
314 square inches
Step-by-step explanation:
The radius is half the diameter. If the diameter is 20 inches, the radius is 20/2 = 10 inches. The area is given by the formula ...
A = πr²
Filling in the given values, we get ...
A = 3.14×(10 in)² = 314 in² . . . . area of the circle
Answer:
the answer is A x=1/2 and y=5/3
Step-by-step explanation:
The equation would be y=-1/5x+2
The slope is always switched to make a line parallel to the first equation
V= pi Times r squared times h
First divide both sides by pi and h
V / pi h = r squared
Square root both sides.
The square root of v /pi times h = r
