what is the surface area of cone with a diameter of 10 centimeters and a slant height of 12 centimeters round your answer to the

Oduvanchick [21]

The surface area of the cone is $266.9cm^2$

Explanation:

The diameter of the cone is 10 cms

Thus, the radius of the cone is given by

$r=\frac{d}{2} =\frac{10}{2} =5$

The slant height of the cone is 12 cms

The formula for surface area of the cone is given by

$S A=\pi r^{2}+\pi r l$

Substituting the values, we get,

$S A=(3.14)(5)^{2}+(3.14)(5)(12)$

$S A=(3.14)25+(3.14)(60)$

$SA=78.5+188.4$

$SA=266.9cm^2$

Thus, The surface area of the cone is $266.9cm^2$

Answer:

There will be $4450 left at the end of the year.

Step-by-step explanation:

We first take 11% and multiply it by $5,000. We get 550. This means that the account will lose $550. Next, we take our original amount, $5,000, and subtract $550 from it. We will get $4450.
