Answer:

1,282.2 m³

Step-by-step explanation:

We'll use the formula 1/3*(B*h)

First, you have to find the area of the base

formula: πr²

radius: 7

7*7= 49

49*3.14=153.86

Now, multiply 153.86 by 25 (the height)

153.86*25= 3,846.5

Lastly, divide 3,846.5 by 3 and get 1,282.2 rounded

What is the value of the geometric sequence for which a1=10 and r=0.5?

tiny-mole [99]

The formula for an infinite geometric sequence is the following:

$S_{∞}= \frac{a_{1}}{1-r}$

Just substitute the values of $a_{1}$ and r into the formula.

$S_{∞}=\frac{10}{1-0.5}$
$S_{∞}=\frac{10}{0.5}$
$S_{∞}= 20$

Therefore, the answer is 20.
