The circumference would be 30 ft, which comes from 6 people have 5ft of space each. 6 x 5 = 30. Which means the diameter is 9.55414013; Circumference divided by pi is the diameter. Once you divide the diameter by 2 for the radius, you get 4.777 which can be used to find the area of the table top. Area is pi x radius x radius = 3.14 x 4.777 x 4.777 =71.654 ft^2
Answer: Small Campground: 15 garbage cans
Large Campground: 45 garbage cans
Step-by-step explanation: If there are 40 picnic tables in a small campground, there should be 15 garbage cans. Because 40/8=5 and 5*3=15. If there are 120 picnic tables in a large campground, there should be 45 garbage cans. Because 120/8=15 and 15*3=45
For big circle the diameter is 10 so the radius is 5. Use the equation for the area of a circle pi r^2.
Pi is 3.14 as said in the question.
So 3.14 x 5^2 or 25 x 3.14=78.5
For smaller circle, diameter is 6cm so the radius is 3.
Using the same area of a circle equation it would equal 3.14 x 3^2 or 9 x 3.14=28.26
Take 28.26 away from 78.5 to get 50.24.
To the nearest tenth would mean it would equal 50.2
The last option is the answer
Answer:
y = - 10
Step-by-step explanation:
2x - 5y + 3 = 6x - 3y + 7
2(4) - 5y + 3 = 6(4) - 3y + 7
8 - 5y + 3 = 24 - 3y + 7
11 - 5y = 31 - 3y
11 - 11 - 5y = 31 - 11 - 3y
- 5y = 20 - 3y
- 5y + 3y = 20 - 3y + 3y
- 2y = 20
- 2y ÷ - 2 = 20 ÷ - 2
y = - 10
