Answer:
Step-by-step explanation:
When a ceiling fan is turned on it sweeps out a circle. That means that this question is asking us to find the area of the circle with a radius of 25 inches.
is the area of a circle. If the radius is 25 inches and pi is 3.14, then
and
A = 3.14(625) so
A = 1962.5 inches square.
In terms of pi, the area is
A = 625π
Answer:
Step-by-step explanation:
the direct variation is will be y varies directly as x and
mathematically
y∝ x
y = kx ........................................ wher k is the constant of proportionality
k = y/x
given that y = 2
x = 8
k = 2/8
k = 1/4
Step-by-step explanation:
it can not be determined
