What is the lateral area of the cone? 10 yd and 12.1 yd
Harman [31]

Answer:

The lateral area will be "381 yd²". A further solution is provided below.

Step-by-step explanation:

The given values are:

Radius of cone,

r = 10 yd

Height of cone,

L = 12.1 yd

As we know,

The lateral surface area of cone is:

=  \pi r L

On substituting the values, we get

=  \frac{22}{7}\times 10\times 12.1

=  \frac{22}{7}\times 121

=  380.28 \ yd^2

0r,

=  381 \ yd^2

Eddi Din [679]

Answer: Choice C

0 \le d \le 2

Graph with filled in circles at d = 0 and d = 2, shading in between

==========================================

Explanation:

d = amount downloaded in gigabytes

The smallest amount is d = 0. We cannot download a negative amount of data, so this is why d = 0 is the smallest.

The largest amount allowed is d = 2. This is the cap that the ISP has set up.

So basically d can be anything between d = 0 and d = 2, including both endpoints. This means 0 \le d \le 2

We use filled in circles for both endpoints to show to the reader "include these endpoints". Shading is done in between to show the entire solution set of possible d values. For instance d = 1 is in that region so it is possible to have this solution. Something like d = 4 is outside the region and not possible.
