Answer:12 5/8
Step-by-step explanation:
Add the whole numbers together. 3 + 9 = 12
Multiply 1/4 so that it will have the same dnominator as 3/8. 2(1/4)= 2/8
Add the fractions together. 2/8 + 3/8 = 5/8.
Add the whole number and fraction to get a mixed number. 12 + 5/8 = 12 5/8

Answer:
diameter = 2.5 feet
Step-by-step explanation:
Circumference of a circle is given as C = πd
Circumference of the tree trunk = 7.85 ft
π = 3.14
Diameter of the tree trunk = d
Thus:
7.85 = 3.14*d
Divide both sides by 3.14
7.85/3.14 = 3.14*d/3.14
2.5 = d
d = 2.5 ft
