Answer:

Given the value of pi (π) = 3.14

Given the speed of Radius = 0.10 mph

Given the total area = 11000 square miles.

To find = the time.

Step-by-step explanation:

Since the oil spill in the ocean and spread in a circular pattern. So the total the spilled area = 11000 square miles.

The speed of the radius at which is increase = 0.10 mph

Given the value of pi (π)  = 3.14

Now we have to find the total hours consumed to cover the area or the spilled over the area.

First, find the radius and this radius will be the distance. Then divide the distance with speed to find the time taken.

Area  = 2 π r^2

11000 = 2 ×3.14 × r^2

r = 41.85 m

Now find the time.

Time taken to spill the oil =  41.85 / 0.10 = 418.52 hours

What is the answer, Shelby made 5 quarts of juice for a picnic. How many cups of juice did shelby make?
Anvisha [2.4K]

Given, Shelby made 5 quarts of juice for a picnic.

We know that 1 quart of juice = 4 cups of juice.

Here we will have to convert 5 quarts to cups.

As for 1 quart there are 4 cups, to find 5 quarts we have to multiply 4 times 5.

So 5 quarts of juice = (4)(5) cups of juice.

We know that, (4)(5) = 20

5 quarts of juice = 20 cups of juice.

We have got the required answer here.

Shelby made 20 cups of juice there in the picnic.
