The surface area of a cylinder is:

$2 \pi rh+2 \pi r^2$

So fill in the equation and solve:

$2 \pi (8)(11)+2 \pi (8)^2$
$2 \pi 88+2 \pi 64$
$\pi 176+ \pi 128$
$\pi 304$
$3.14*304$
$954.56 cm^2$

Hope this helps!

How to find the rule for the nth term of a geometric sequence with changing common ratio?

ki77a [65]

Hmmm... a geometric sequence MUST have a fixed common ratio. If it is changing, then the sequence you are looking at might not be a geometric sequence at all. We'd need to see an example to be sure.

Help me to answer this pls

The 6 angles with vertex P are:

Angle APB
Angle APC
Angle APD
Angle BPC
Angle BPD
Angle CPD

The letter P must be in the middle since this location is the vertex. Something like angle BPA is the same as angle APB. We can swap the order of the outer letters without any change to the angle itself. Effectively, this means each angle has two possible names.

Lily bought 20.24 pounds of grapefruit. The lightest grapefruit weighed 1.2 pounds. The heaviest grapefruit weighed 1.8 pounds.

Given:

Lily bought 20.24 pounds of grapefruit.
The lightest grapefruit weighed 1.2 pounds.
The heaviest grapefruit weighed 1.8 pounds.

To Find:

An estimate of the number of grapefruits she bought.

Answer:

The best estimate is that Lily bought 13 grapefruits.

Step-by-step explanation:

Given that the lightest grapefruit weighed 1.2 pounds and the heaviest one weighed 1.8 pounds, we can take the mean or average of these two weights to estimate the weight of any of the grapefruits that she bought.

That is, we can say that each grapefruit must weigh something close to the average value.

The average can be found as

$\frac{1.2+1.8}{2}=1.5$
