Step-by-step explanation:

From the given diagram, the radius of the given circle is 4 cm.The perimeter of any given circle is calculated by multiplying 2π with the radius. The radius of this circle is 4 cm and it says π = 3.142The Perimeter for the given circle = 2π × r = 2 × 3.142 × 4 cm = 6.284 × 4 cm = 25.136 cm.                                                       Rounding this off to one decimal 25.136 square cm, the perimeter equals 25.1 square cm.
