Answer:
e
Step-by-step explanation:
e
Mixed # x denominator + numerator = imp. Fraction
28 x 14 = 392 + 11 = 203
203/14 = 29/2 = 14.5
The correct answer is the option D, which is: <span>D. 78 cm; 39 cm; 30.3π cm
The explanation is shown above:
1-The formula for calculate the circumference of a circle is:
C=2</span>πr
78π=2πr
2- The radius is:
r=78π/2π
r=39 cm
3- The diameter is:
D=39 cm x 2
D=78 cm
4- The arc length is:
arc length=(140°π/180°)(39 cm)
arc length=30.3π cm
