Answer:

The circumference of a circle with radius 48 is 301.6(*)

Explanation:

Formulas:

  • d = 96
  • C = 302
  • C = 2·π·r C = π·d C = √4·π·A π = 3.1415
  • A = area of the circle
  • C = circumference or perimeter
  • r = radius, d = diameter

Step-by-step Solution:

  • Circumference of a cicle in terms of radius:
  • Circumference = 2·π·r = 2·3.14·48 = 301.58(*)
  • In terms of diameter:
  • Circumference = π·d = 3.14·96 = 301.44(*)
  • In terms of area:
  • Circumference C = √4·π·A = √4·π·7238 = 301.58(*)

(*) 301.6 cm exactly or limited to de precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

A circumference of 301.6 centimeters is equal to:

  • 0.003016 kilometers (km)
  • 3.016 meters (m)
  • 3016 millimeters (mm)
  • 0.00187406 miles (mi)
  • 3.29834 yards (yd)
  • 9.89501 feet (ft)
  • 118.74 inches (in)

Answer:

301.6

Explanation:

circumference = πD

Diameter = r x 2

diameter = 48 x 2 = 96

96 x π = 301.592895

301.6 to 1dp
