Answer:

see explanation

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

Please help!!!!!! ASAP
ICE Princess25 [194]

Answer:D

Step-by-step explanation:

Radius=r=8

Φ=2π/3

π=180

2π=360

length of arc=Φ/360 x 2 x π x r

Length of arc=(2π/3 ➗ 2π) x 2 x π x 8

Length of arc=(2π/3 x 1/2π) x 2 x π x 8

Length of arc=((2πx1)/(3x2π)) x 2 x π x 8

Length of arc=2π/6π x 2 x π x 8

Length of arc=1/3 x 2 x π x 8

Length of arc=(1 x 2 x π x 8)/3

Length of arc=16π/3
