Answer:12
Step-by-step explanation:
Answer:
32π cubic units
Step-by-step explanation:
Given: r=4, h=6, v=?
Volume of cone: v=(h*πr²)/3
Substitution: v=(6*π*4²)/3
v=2*π*16
v=32π unit³ or approx. 100.530965 unit³
Answer:
326
Step-by-step explanation:
First you find the area of the triangles. Since squares have equal sides we know that the triangle has a side of 20 and 12. We plug this information into the formula A=20x12/2 which equal 120 but since we have 2 triangles we multiply by 2 and get 240. Then we find the area of the square which is 400 when you multiply 20x20. Then you find the area of the circle which is 3.14x10^2 which equals 314. You add 240 and 400 to get 640. You subtract 460 from 314 and get 326.
The answer is 2.35. 4.23/1.8 = 2.35
