0.80
9 in 0.79 is the tenth place. Since 9>5, upon rounding up 0.79 to the nearest tenth, 0.80 would be the answer.
Answer:
Circumference of circle = (15.5)π cm
Step-by-step explanation:
Missing information:
Area of circle = 60π cm²
Find:
Circumference of circle
Computation:
Area of circle = πr²
Area of given circle = π(Radius of circle)²
60π = πr²
60 = r²
Radius of circle = 7.75 cm (Approx)
Circumference of circle = 2πr
Circumference of circle = 2(π)(7.75)
Circumference of circle = (15.5)π cm
Answer:
Step-by-step explanation:
If this was an entire circle, the area could be found by using
Area = pi * r^2 where r = 9
To take the central angle into account, use this formula
Area = 120/360 * pi * r^2
Area = 1/3 * pi * 9^2
Area = 27 pi
area = 84.78 cm^2 which isn't there.
