Answer:
-1
Step-by-step explanation:
You go down 1 ( which is why it's -1) and then over 1 so it would be -1/1 or simplified as -1
Answer:
31.42 cm (rounded up to two decimal places)
Step-by-step explanation:
We first find the circumference of the semi-circle segment:
The circumference will be given by; × π × D (where D is the diameter)
The diameter is 6 cm so circumference is;
× π × 6 cm = 9.42 cm (rounded up to two decimal places)
The perimeter of the figure therefore is;
8cm + 6 cm + 8 cm + 9.42 cm = 31.42 cm
Answer:
C. p = 1.72d
Step-by-step explanation:
The rate of change for the diver is 0.43. 0.43 x 4 = 1.72d.
Answer:
= 18.857 cm²
Step-by-step explanation:
The area of a segment is given by;
θ/360 × 2πr². where θ is the angle subtended by the arc to the center of the circle and r is the radius of the circle.
θ = 60, and r = 6
Therefore;
Area = 60/360 × 22/7 × 6²
= 18.857 cm²
I don't think those two expressions would even be equal unless w = 0. You can't just add in a 2 from nowhere.
