Question

Brainliest if correct!!!!!

Answer 1

Answer:

3.14159

Step-by-step explanation:

A) Pi value using circumferences

C = circumference

d= diameter

Formula: C = Pi*d⇒Pi = C/d

Circle A)

Pi = 21.98/7 = 3.14

Circle B)

Pi = 18.84/6= 3.14

B) Using areas

A = area

r = radio = diameter/2

Formula: A = Pi*(r^2 )⇒ Pi = A/(r^2)

Circle A

Pi = 38.465/(3.5)^2= 3.14

Circle B

Pi= 28.26/(3^2)= 3.14
