A11-foot ladder is leaning against a building, with the base of the ladder 6 feet from the building. how high up on the building will the top of the ladder reach? round to the nearest tenth

9.2 feet

Step-by-step explanation:

This is a Pythagorean theorem question

The ladder is the hypotenuse or c

the distance from the wall is a leg or a

and the wall is the other leg or b

a² + b² = c²

6² + b² = 11²

36  + b² = 121

-36             -36

          b² = 85

         √        √

          b = √85

           b = 9.2 feet

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
