Answer:
(9,3)
Step-by-step explanation:
Answer:
(1) To south-west is 135°
(2) To south is 180°
Answer:
66 cm (Option B)
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr, so plug the values into the formula. The radius, (r) of a circle is one half of the diameter, so split 21 is half to get a radius of 10.5. Use 3.14 for π.
C = 2πr
C = 2(3.14)(10.5)
C = 6.28 × 10.5
C = 65.94
Rounded to the nearest unit, you get a answer of 66 cm.
Hope this helps! :)
Answer:
We need approximately 201 ft of fencing
Step-by-step explanation:
We need to find the circumference of the pool plus the fence
C = 2*pi *r where r is the radius of the pool and the fence
r = 28 +4 = 32
C = 2 * pi * (32)
C = 64 pi
Letting pi =3.14
C = 64*3.14
C =200.96 ft
Rounding to the nearest foot
We need approximately 201 ft of fencing
