Step-by-step explanation:
the value of π is 3.142...
multiply this value with the squared radius of the circle and you'll get your answer.
For example:
we have a circle with diameter 5
so, π x 5² = 3.142 x 25 = 78.5

Perimeter:
P = 2(W + L)
P = 2(3.5 + 6.5)
P = 2(10)
P = 20 units
Area:
A = WL
A = 3.5 * 6.5
A = 22.75 square units
