Find the total area of the solid figure. 78 sq. in. 90 sq. in. 60 sq. in.
yaroslaw [1]

The total area of the figure will be 245 sq. in.

<h3>Total area of a cylinder</h3>

The figure is a cylinder and the total area of a cylinder is given by the formula below:

Total Area of a cylinder = 2πrh+2πr^2

Where r is the radius, h is the height of the cylinder, and π is constant with a value of 22/7.

In this case, looking at the image, the radius is 3" while the height is 10". Substituting these values into the formula above, we have:

Total Area = 22/7((2x3x10) + (2x3^2)) = 22/7(60+18)

           = 245 sq. in.

Thus, the total area of the solid figure is 245 sq. in.

Morgarella [4.7K]

Answer:

People can spread false information and people can upload explicit, inappropriate pictures.

Explanation:

<em>False information</em> - Sometimes people can abuse social media by spreading rumors about people, or causing mayhem that may not be factually correct. You should look out for this and avoid it by using credible sources and checking the website credentials.

Explicit Images and Videos - People can also abuse social media platforms by posting things that are not fit for the general environment. A good rule is make choices that build others up and support them!

Svet_ta [14]
Assuming the riding position pertains to biking, the best position for the elbows is bending them. In doing so, you would relieve some pressure on your elbows, wrists and hands. This could also help you absorb shock when passing over bumpy roads through your arms.
