Answer:

  502

Step-by-step explanation:

It depends on the arrangement.

If a tree is planted in the middle of each 20 m space, then you get one answer. If a tree is planted at the ends of each 20 m space, then you get a different answer.

Here, we will assume that a tree is planted at the ends of the road and every 20 m in between. Then the number planted on one side of the road is ...

  1 + (5000 m)/(20 m) = 251

And the number of trees planted on both sides of the road is ...

  2 × 251 = 502 . . . trees planted altogether

_____

<em>Additional comment</em>

If _ represents a 10 m space, the arrangements we're talking about above are ...

   _T_ . . . tree in the middle of the space

  T_ _ T . . . trees at the end of the space

Knowing that a tree requires room to spread out, we might choose the former arrangement. That would mean a total of 500 trees, rather than 502.

A large pizza has a diameter of 14 inches. A medium pizza has a diameter of 10 inches. How much larger is the area of the large
Arte-miy333 [17]

Answer:

The bigger pizza has a diameter of 14 inches, or a radius of 14 / 2 = 7 inches.

The smaller pizza has a diameter of 12 inches, or a radius of 12 / 2 = 6 inches.

Step-by-step explanation:

The area of a circle is πR2 where R is the radius.

The difference in the size of the pizzas is  

Area of bigger pizza - Area of smaller pizza

= π(7 inches)2 - π(6 inches)2 = = 49π inches2 - 36π inches2 = 13π inches2
