The distance around the middle of a sphere (the circumference) equals 37.699 in. what is the surface area of the sphere?
podryga [215]

To solve this problem you must apply the proccedure shown below:

1. Clear the radius from the formula for the circumference of a circle and substitute values, as following:

C=2\pi r\\ r=C/2\pi \\ r=37.699in/2\pi \\ r=5.99in

2. Substitute the radius calculated into the formula for calculate the surface area of the sphere:

SA=4\pi r^{2} \\ SA=4\pi(5.99in^{2})\\ SA=450.88in^{2}

The answer is: 450.88in^{2}

Three friends went apple picking and then counted the apples they picked.Who had the largest red to green apple ratio? Use compl
antoniya [11.8K]

Answer:

Carmen had the largest red to green apple ratio of 5 : 3

Step-by-step explanation:

Red apples : Green apples

Carmen = 20 red apples : 12 green apples

= 20 / 12

= 5 / 3 = 1.67

= 5 : 3

Dylan = 12 red apples : 10 green apples

= 12 / 10

= 6 / 5 = 1.2

= 6 : 5

Eli = 16 red apples : 20 green apples

= 16 / 20

= 4 / 5 = 0.8

= 4 : 5

Carmen had the largest red to green apple ratio of 5 : 3

Suppose the leftmost digits of two numbers are 8 and 3. Can you tell which numbers is greater. Explain
Svetach [21]
No:
At first, it might appear that the number with a leftmost digit of 8 should be bigger than one with a left most digit of 3 because so long as the 3 and 8 have the same digit position, this will be the case;
The same applies if the 3 is at a lower digit position than the 8;
But, there is nothing in the statement to suggest that the 8 has the higher digit position, i.e. the numbers could be 3000 and 800;
In this case, the largest number has the leftmost digit of 3;
Therefore, you cannot tell which number will be bigger without any other information.
