Step-by-step explanation:
Considering it's volume of 113 cm³, the approximate radius of the sphere is given by:
A. 3 cm
<h3>What is the volume of an sphere?</h3>
The volume of an sphere of radius r is given by:

In this problem, we have that V = 113 cm³, hence the radius in cm is given as follows:



![r = \sqrt[3]{\frac{113 \times 3}{4\pi}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B113%20%5Ctimes%203%7D%7B4%5Cpi%7D%7D)
r = 3 cm.
Hence option A is correct.

Answer:
The n-th term of this sequence appears to be
3
n
−
1
,
n
≥
1
.
Step-by-step explanation:
These are powers of
3
ordered from
3
0
=
1
to
3
a
(for an integer
a
≥
1
). However, the first convenient value for
n
is
1
, not
0
(imagine saying the 0th term of a sequence). Because of that, since the first term is actually
3
0
, we need to start from the first term (
n
=
1
) being
3
1
−
1
. The next is
3
2
−
1
,
