Answer:450 cm
Step-by-step explanation:
Assuming that the balls are perfect sphere, then we can use the formula for the volume of the sphere to solve the volume of the ball. the volume of a spher is given by the formula:
V = (4/3) pi r^3
where pi = 3.1416
r is the radius
since D = 9 in
r = 4.5 in
V = ( 4/3 ) (3.1416) ( 4.5)^3
V = 381.7 cubic inches is the volume of one of the balls.
Answer:
It is 121
Step-by-step explanation:
<u>Solution-</u>
The atmospheric pressure at sea level = 14.7 lb/in²
Pressure gets reduced by half for each 3.6 miles we move up.
Taking,
x = miles above the sea-level
y = pressure in lb/in²
0 14.7
3.6 7.35
7.2 3.675
10.8 1.8375
It can be observed that both the variables are in inverse proportion as the distance from sea-level increase the pressure decreases.
As only the second graph satisfies the points and inverse proportional condition, so that is the correct graph.
By plotting the graph in excel taking these data set, the following plot was obtained.
Answer:
no
Step-by-step explanation:
for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse
a² + b² = c²
in this problem, 4² + 10² ≠ 11²
16 + 100 ≠ 121
