<span>I guess the answer is 96m square because you need to multiply length by width</span>
The answer is 8 cm because the radius of the circular opening is 4 cm.<span />
Answer:
arc ABC = 196°
arc DC = 360 - 196 - 70 = 94° (which looks out of proportion, but so does angle D)
Step-by-step explanation:
arc ABC = 2(∠D) = 2(98°) = 196°
Answer:
She will need approximate 
of plastic border
Step-by-step explanation:
we know that
The circumference of a circle is equal to
In this problem we have
substitute
----> exact value of the length of plastic border
assume
---> approximate value of the length of plastic border
Answer:
B)
4.5 cm
Step-by-step explanation:
The formula for arc length when our central angle is in degrees =
2πr(θ/360)
θ = 86°
Diameter = 6cm Radius = Diameter /2
Radius = 6cm/2 = 3cm
Hence,
Intercepted arc length = 2 × π × 3 (86/360)
= 2 × π × 3 × 0.2388888889
= 4.5029494701 cm
Approximately = 4.5 cm
Option B is the correct answer
