A pizza has a diameter of 14 inches each piece has a central angle of 30° what is the distance around the outside of the crust t

jonny [76]

Answer:

The distance is 2.33 π

Step-by-step explanation:

First we have to calculate the perimeter of the circle with the following formula:

r = 14in

c = π * 2r

Now we replace the value of r

c = π * 2 * 14

c = π * 28

c = 28π

Now we have to multiply it by 30/360 which is the fraction that represents the arc over the entire circumference

28π * 30/360 = 2 1/3 π = 2.33 π

Sam can mow a lawn in 30 minutes. Rocky can mow the same lawn in 90 minutes. How long does it take for both Sam and Rocky to mow

Anvisha [2.4K]

Answer:

$\frac{45}{2} \ minutes$

Step-by-step explanation:

Given:

Sam can mow a lawn in 30 minutes.

Rocky can mow the same lawn in 90 minutes.

Question asked:

How long does it take for both Sam and Rocky to mow the lawn if they are working together?

Solution:

By unitary method:

For Sam

Sam can mow in 30 minutes = 1 lawn

Sam can mow in 1 minute = $\frac{1}{30}\ lawn$

For Rocky

Rocky can mow in 90 minutes = 1 lawn

Rocky can mow in 1 minutes = $\frac{1}{90} \ lawn$

In a case of working together:

In 1 minute, both will mow = $\frac{1}{30}\ lawn$ + $\frac{1}{90} \ lawn$

= $\frac{3+1}{90} = \frac{4}{90} \ lawn$

To mow $\frac{4}{90} \ lawn$ together, it takes = 1 minute

So, to mow 1 lawn together, it takes = $\frac{1}{\frac{4}{90} } =\frac{90}{4} =\frac{45}{2} \ minutes$

Thus, both Sam and Rocky will mow the lawn together in $\frac{45}{2} \ minutes$
