Answer:
Radius is 8 cm, this means that the diameter is 16 cm. the circumference formula is 2(pie)R 2x3.14xRadius... Your answer is 50.265CM
Step-by-step explanation:
Answer:
i'm pretty sure that it is 27 due to vertical angle theorem
let me know if its right :)

Step-by-step explanation:
(1)
Calculate the circumference (C) of the wheel
C = πd (d is the diameter )
= 3.14 × 8 = 25.12 cm
Now divide the distance travelled by the circumference.
times rotated = 12560 ÷ 25.12 ≈ 500
----------------------------------------------------------------
(2)
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Find r by using the circumference (C)
2πr = 50.24 ( divide both sides by 2π )
r = 50.24 ÷ 6.28 = 8 , then
A = 3.14 × 8² = 3.14 × 64 ≈ 200.96 ft² ( student 3 )
-----------------------------------------------------------------
(3)
C = πd = 3.14 × 30 = 94.2 ≈ 94 m
