I don't know but I know it is going to be a lot
It should be 0.4 cause 0.4 is the same as 0.40
The answer is 6.28318530718.
2 x pi (3.14159 etc.,) equals 6.28318530718...
The answer is C
1/2(5x + 12)
because the perimeter is equal 20x + 6
The perimeter of the given circle is 25.1 square cm.
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 = 3.142
- The 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.
