Answer: The radius of the ball is 7 meters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a sphere: 4 π r^2
Replacing with the value given:
615.75 = 4 π r^2
Solving for r (radius):
615.75 /4π= r^2
√(615.75 /4π) =r
r = 6.99 = 7m (rounded)  
The radius of the ball is 7 meters.

Answer:
1:10 pm 
Step-by-step explanation:
<em>60 minutes in an hour</em>, so 
8:50am + <u>4 hours</u> = 12:50pm 
12:50pm + <u>20 minutes</u> = 1:10pm
 
        
             
        
        
        
For this case we have to:
There are 6 plants per tray.
There are 6 trays for each flat, so for each flat there are 
 plants.
Saturday day:
Thus, on Saturday they sold 648 plants.
Sunday: 
Thus, on Saturday they sold 756 plants.
Thus, in total 
plants were sold.
Answer:
 plants were sold.

Based on the picture, we know that ED is equal to DB. Therefore:
2 times ED=EB
2(10)=20
EB is 20
