A spherical ball just fits inside a cylindrical can,16 centimeters y'all, with a diameter of 16 centimeters. What is the express

Veseljchak [2.6K]

Answer:

The correct answer is the expression of the volume of the sphere is $\frac{4}{3}$ ×π× $8^{3}$ and the expression of the volume of the leftover space is π× $8^{3}$ ×16 - $\frac{4}{3}$ ×π× $8^{3}$ .

Step-by-step explanation:

Height of the given cylindrical can = 16 cms.

Diameter of the given cylindrical can = 16 cms.

Now a spherical ball just fits in this given cylindrical can. Thus the diameter of the ball is equal to the diameter of the can, equal to 16 cms.

Thus the expression of the volume of ball = $\frac{4}{3}$ ×π× $r^{3}$ = $\frac{4}{3}$ ×π× $8^{3}$

Expression of the volume of the cylindrical can is π× $r^{3}$ × h = π× $8^{3}$ ×16

Expression of the leftover volume would be volume of can minus volume of the ball = π× $8^{3}$ ×16 - $\frac{4}{3}$ ×π× $8^{3}$ .

maw [93]

Given :- 50% of all voters are democrats.

Probability that randomly selected voter will be a democrat = 0.50.

Independent event Property :- If two events A and B are independent on each other then P(A and B) = P(A) * P(B).

In this question, Vote of one person is independent on another person. Every individual's vote preference is independent.

The probability that they are both democrats

= P( first is democrat AND second is also a democrat)

=P(first is democrat) * P(second is also a democrat)

= 0.50 * 0.50 (Using above property of independent events)

= 0.25

Answer :- If two voters are randomly selected for a survey, Then the probability that they are both democrats is 0.25.

The length of a rectangle is 1ft less than 3 times the width. There is 310 ft squared.Find the dimension of the rectangle.

lozanna [386]

Answer:310

Step-by-step explanation:

l=-1+3w

l=3w-1

l*w=310

(3w-1)*w=310

3w^2-w-310=0

w= 31/3

w= 10 1/3

l=31/3*3-1

l=30

30*31/3=10*31=310
