Answer:
115
Step-by-step explanation:
angle DEF is an inscribed angle and arc DF is the arc it intercepts
if you didn't know an inscribed angle is equal to half the measure of the arc it intercepts
Hence angle DEF = 1/2 of arc DF
If arc DF = 230 then angle DEF = half of 230 or 230/2
230/2=115
Hence angle DEF = 115

Answer:
PI×(RADIUS) 2
Step-by-step explanation:
RADIUS = 6/2 = 3 FEET
The area of the larger square is x^2
The area of the small square is 3*3 = 9
To find the area of the shaded region you subtract the two values.
x^2 - 9
The factored form of this is (x + 3)(x - 3)
