Area of a circle in terms of radius:
Area = π · r2 = 3.14 · 1.072 = 3.57 square meters.
In terms of diameter:
Area = π · (d
2
)2 = 3.14 · (2.13
2
)2 = 3.14 · (1.07)2 = 3.57 square meters.
In terms of circumference:
Area = C2

= 3.57 square meters.
Note: for simplicity, some results may be rounded to nearest hundredth and π was rounded to 3.14. See formula details below in this page.

Circle area formula
Answer:
b - 1/4 = 3 1/2
Step-by-step explanation:
b - 1/4 = 3 1/2
b - 1/4 = (3 + 1/2)
4b = 15
b = 15/
4
= 3.75
