Answer:
6 cm
Step-by-step explanation:
The diameter is 2x the radius
Least to greatest: 5 10/11 , 5.822 , 5.84, 117/20.
Question 7:
Diameter = 6.2 cm so Radius = 3.1 cm
A=πr² = 3.14 × 3.1² = 30.1754 cm² = 30.18 cm²
Question 8:
Circumference = 2πr
16π = 2πr
therefore 16 = 2r so r = 8cm
3 and 4/8 for question number one
