What is the volume, in cubic cm, of a cylinder with a height of 8cm and a base radius of 7cm, to the nearest tenths place?

FromTheMoon [43]

Answer:

Volume of the cylinder = $1230.88\,cm^3$

Step-by-step explanation:

Height(h) of the cylinder = $8 cm$

Radius(r) of the base= $7cm$

Volume of a cylinder is:

= $\pi \times r^2\times h$

As,

$\pi =\dfrac{22}{7} = 3.14$

Putting the values in the formula:

Volume is:

$=3.14\times(7\times7)\times8\\\\=3.14\times49\times8\\\\=3.14\times392\\\\=1230.88\,cm^3$

The volume of the cylinder is : $1230.88\,cm^3$

What is the 6th term of the geometric sequence 4, −20, 100, ...?

shtirl [24]

Let's calculate r of this G.P: (-20)/(4) = - 5(100)/(-20) = - 5So r = -5
The formula to find the nth term of a GP is;
a(n) = a(r)ⁿ⁻¹
<u />a₆ = a(r)⁶⁻¹
a₆ = 4(-5)⁵ = -12500<u />
