we need to find the area of a circle with a radius of 21.
we also need a formula for this, which is
⇒
the known value is r, radius, 21.
after substituting the value into the formula, we obtain:
⇒
now we multiply the radius times itself:
⇒

Answer: No triangle
Step-by-step explanation:
The given dimensions of triangle : 4.8 cm, 2.1 cm, and 2.6 cm
- The famous triangle inequality says that in any triangle the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side.
But
It means the sum of two sides (2.1 and 2.6) is less than the third side (4.8).
Therefore by triangle inequality, no triangle can be possible by the given measurement.
