Agiant sequoia (scientific name: sequoiadendron giganteum) is exactly as its name suggests- giant! currently, the "general sherman" tree, thought to be one of the largest giant sequoias in the world, resides in the sequoia national park, which is located in northern california. the tree's largest circumference, located near the base of the trunk, measures approximately 102.6 feet!

use scientific notation to represent the circumference of the general sherman's trunk in inches. include all of your calculations in your final answer.

answer:

  1.2312×10³ inches

step-by-step explanation:

(102.6 ft)×(12 in/ft) = 1231.2 in = 1.2312×10³ in

you can set your scientific or graphing calculator or any spreadsheet to display in scientific notation.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
