Answer:
138.3ft^3
Step-by-step explanation:
Volume for cylinders : V = pi*r^2*h
Volume for cones : V = pi*r^2*(h/3)
Since we know the radius (r) is 2 and the height is 10 and 3 for the cylinder and cone respectively, all we do is plug in.
Volume for cylinder is about 125.7ft^3
Volume for cone is about 12.6ft^3
Then just add them together for a total of 138.3ft^3
Answer:
0.75 Miles
Step-by-step explanation:
To find the answer we have to find the difference in the distance the train and car travelled
65/60 is 1.083333 which is miles per minute then multiplied by 3 is 3.25 mile gone in 3 minutes
For the train it is 50/60 which is 0.833333 and the times 3 is 2.5 miles in three minutes
3.25 miles minus 2.5 miles is 0.75 miles so that is how long the train is
Answer:
x=12
Step-by-step explanation:
Answer:
12 units²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 4 ( perpendicular distance between the bases ) and
b₁ = SR = 2, b₂ = TA = 4 , then
A = × 4 × (2 + 4) = 2 × 6 = 12 units²
