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
The answer would be C and E
Answer:
distance is 6.4 units
Step-by-step explanation:
use a^2+b^2=c^2 to find the hypotenuse which is the distancr
you can count the sides base is 4 and height is 5 Square the numbers
16+25= c^2
41=c^2
find the square root of 41 to get rid of the squared
which is 6.40 so 6.40= c and c is the distance
