1188 = πr²h

For the formula to solve for h, you have to change the equation to:

h = 1188/πr²

which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.

because h was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)

Since you don't know the radius, you can't simplify this equation.

The answer is h = 1188/πr²

-Dominant- [34]

The distance traveled by the center is equal to the distance traveled by the wheel 6.28m is traveled by the center.

Given: A wheel with a radius rolled in a straight line through one complete revolution on a flat horizontal surface.

To Find: How many meters did the center of the wheel travel horizontally from its starting location.

Solution:

consider the figure attached.

radius of wheel $=1m$

Horizontal distance traveled by the wheel in one complete revolution

=circumference of the wheel

$\\=2\pi r\\=2*3.14*1\\=6.28m$

Hence, the distance traveled by center is equal to the distance traveled by the wheel 6.28m is traveled by the center

Answer:

This indicates that the chances of the mean life span today is greater than 70 years is 0.5871

Step-by-step explanation:

The past year showed an average life span of 71.8 years.

$\mu = 71.8 years$

Population standard deviation = 8.9 years

$\sigma = 8.9 years$

We are supposed to find the mean life span today is greater than 70 years

i.e. P(X>70)

Formula : $Z = \frac{x-\mu}{\sigma}$

$Z=\frac{70-71.8}{8.9}$

Z=−0.202

P(X<70)=0.4129

P(X>70)=1-P(X<70)=1-0.4129=0.5871

Hence This indicates that the chances of the mean life span today is greater than 70 years is 0.5871
