A5 / a1 =  r^4  = 324/4 

So r^4 = 81

r = +/- 3

If  r = 3 :-

S5  = 4 *  (3^5-1) / (3-1)  = 484

so r = 3 Answer

What is the area of the beach ball with a diameter of 14 in. ?
Juliette [100K]

Answer:

The answer is 675.75 square Inches

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • Diameter (d) = 14 in.
<h3><u>To </u><u>Find</u>;</h3>
  • Area of beach ball = ?
<h3><u>Formula</u>;</h3>
  • Area = 4πr²

Now,

Radius (r) = diameter ÷ 2

r = 14/2 in.

r = 7 in.

Now,

A = 4πr²

A = 4 × 22/7 × (7)² in.

A = 4 × 22 × 7 in.

A = 615.75 square in.

Thus, The area of the beach ball with a diameter of 14 in. is 615.75 square in.

Elie went bowling with $25 to spend. He rented shoes for $5.25 and paid $4.00 for each game what was the greatest number of game
nalin [4]

Answer:

The greatest number of games Elie could have played was 4.

Step-by-step explanation:

This is because if you take 25 and subract the 5.25, you would get 19.75. In order to get the max games Elie could play, you would divide 19.75 by 4, since each game is $4. You would end up with 4.9, but would have to round down since you can't round up.
