Given:
- Outer diameter = D = 80 ft
- Inner diameter = d = 40 ft
So,
Outer radius = R = D/2
=> R = (80 ft)/2
=> R = 40 ft
Inner radius = r = d/2
=> r = (40 ft)/2
=> r = 20 ft
Area of paved pathway = πR² - πr²
= π(R² - r²)
= π(R + r)(R - r)
= π(40 + 20)(40 - 20) ft²
= π(60)(20) ft²
= 3.14 * 1200 ft²
= 3768 ft²
15:33 10:22 60:132 are some
Answer:
20 pizzas
Step-by-step explanation:
100% of the pizzas were made with extra cheese.
20 pizzas had extra cheese
100% of 20 = 20
So... 20 pizzas
A and C should be the answer, hope this helps
Answer:
Step-by-step explanation:
Given is a picture of circle with angle
BOC =7x-11
Also angle of arc BC = angle BOC = 3x+53
Since both are the same equate the two

Now substitute this x value in any one of 3x+53 or 7x-11
Angle COB = angle BOC = 3x+53
= 48+53 = 101 degrees
-------------------------
To find length of arc
Central angle = 101
Hence arc lengh =
