Answer:
Step-by-step explanation:
Area of circle = π r²
r = 30
30² = 900
π = 3.14 or ≈ 3
A ≈ 900 × 3
A ≈ 2700
so C at 2830 is closest to the answer
633,360,000 divided by 10,000= 63,360inches per mile
Chevy- 63,360 divided by 113.04= 560.5 times 10,000=5,605,000 rotations per mile
Bicyle- 63,360 divieded by 94.2= 672.6 times 10,000=6,726,000
Motorcycle- 63,360 divided by 100.48=630.6 times 10,000= 6,306,000

Answer:
Length = 64 cm , width =16 cm
Step-by-step explanation:
Given Perimeter = 160
Let width = x
Length = 4x
Hence perimeter =2 (length) +2 ( width)
160 = 2(4x)+2(x)
160 = 8x + 2x
160 = 10x
160/10 =x
16 = x
Hence width = 16 cm
Put the value of x in 4x
Length= 4(16)
Length =64 cm
Hence length = 64 cm, width =16 cm
