circumference= 2(pi)r OR (pi)d
d is diameter and r is radius
if the circumference is given, then you would have to work backwards.
in this case, Circumference = 78.5 ft
the equal you would use for the radius would be 78.5 = 2 x 3.14(pi) x r
- multiply 2 x 3.14 and get 6.28
- divide 6.28 on both sides to get ‘r’ by itself
- 12.5 = r
next, for the diameter you can use C= (pi) x d
- 78.5 = 3.14 x D
- divide 3.14 on both sides to get ‘d’ by itself
- 25 = d
hope this helps! make brainliest please
Answer:
W =1 1/4Step-by-step explanation:
Let W = what
W - 1/2 = 3/4
Add 1/2 to each side
W -1/2 +1/2 = 3/4+1/2
W = 3/4+1/2
Getting a common denominator of 4
W =3/4+1/2*2/2
W =3/4 +2/4
W = 5/4
Changing to a mixed number
W = 4/4 +1/4
W = 1 +1/4
W =1 1/4
