The surface are of the right cone is 176 sq.units. Option A) is the correct answer.
<u>Step-by-step explanation</u>:
<u>step 1</u> :
Radius of the cone, <em>r = 4</em>
Height or length of the cone,<em> h = 10</em>
<u>step 2</u> :
Total surface area of right cone = πrh + πr^2
= (π
410) + ( π4^2)
= 40π + 16π
= 56 π = 563.14
= 176 sq.units
The answer is actually choice B. To solve for the area of a trapezoid, you would do the formula a+b/2 h.
Well the probabilities of one or more different outcomes have to add up to 100%. You can't have one outcome be 90% and another be 20% because it does not equal 100%.
So if you know the percentage of one outcome you have to subtract that from 100%
That means C is your answer.
129,407 because 12 ten thousands=120,0008 thousands= 8,00014 hundreds= 1,400No tens=07 ones=7
(x-6)(x+6)
solve just to make sure
x^2+6x-6x-36
combine like terms
x^2-36
