Answer:
Step-by-step explanation:
Area = angle / 360 * pi * r^2
angle = 45
r = 2
pi = 3.14
Area = 45 / 360 * 3.14 * 2^2
Area = 365.2 / 360
Area = 1.57 square inches.
Answer:
a = π/2 in² Exact answer
a = 1.5707963268 in² Decimal approximation
Step-by-step explanation:
a = (∅/360) * πr²
a = (45/360) * π(4)
a = π/2 in² Exact answer
a = 1.5707963268 in² decimal approximation
