Answer:
37.69 (≈ 38 ft²)
Step-by-step explanation:
2πr = 30.77
r = 30.77 / (2 * 3.14) = 4.9
half of free-throw circle area: πr² / 2 = (3.14 * 4.9²) / 2 = 37.69 (≈ 38 ft²)
Answer:
All Triangles are closed figure polygons that have three straight sides
Step-by-step explanation:
All 2D shapes are plane figures so this one is false. Three right angles are greater than 180 so this is fake. Polygon and closed figures are shapes with three or more closed sides. And triangles have straight sides.
Direct variation means their ratio is a constant
x/y is 9/45=1/5
so when x=2, y=5*2=10
WORK
5π/12
75∘⋅π/180∘=5π/12
Therefore the answer not rounded is 1.309 radians
To work out the estimate cost you need do 200 * 5=$1000
then I used a calculator and the actual answer is $895
