Answer: 11.66ft
Step-by-step explanation:
6squared=36+100=136
square root of 136= 11.66ft
Answer:
What is the question??
Step-by-step explanation:
We use the ratio x:360 to find portions of the circle (again, through the ratio)
so we use 60/360 = x/30 in^2
1/6 = x/ 30
x = 5.
The answer is 5 in^2
Answer:
11.2square feet
Step-by-step explanation:
Area of a sector = theta/360 * πr²
theta is the central angle = 80degrees
radius r = PC = 4ft
Substitute
Area of the sector = 80/360 * 3.14 * 4²
Area of the sector = 80/360 * 3.14 * 16
Area of the sector = 4,019.2/360
Area of the sector = 11.2ft²
Hence tthe area of the blue sector is 11.2square feet
161 - 49 = 128
128 / 2 = 64
64 + 64 +49 =161
first number is 64
second is 113
