The umber 10.5 can be written as
==> 21 / 2
==> 42 / 4
==> 63 / 6
==> 84 / 8
==> 105 / 10
and many, many other ways.
They ALL have the same value.
Multiply by 0.4 on both sides to cancel the original 0.4 and change the 10
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.
