Answer:
I think Its 47? if Im wrong Im very sorry.
Step-by-step explanation:
I added all of the numbers, and the sides without numbers, its simple just add all of the numbers together, I think
*) 2/4+3i
2+3i
I'm not sure is that right or wrong
Answer:
pretty sure its D. 1.6 x 10^9
If the original side length is "s" and the original slant height is "h", the original surface area is
.. S = (base area) +(lateral area)
.. S = s² +(1/2)*(4s)*h
.. S = s(s +2h)
Now, if we make these replacements: s ⇒ 3s, h ⇒ h/5, we have
.. S' = (3s)(3s +2h/5)
.. S' = 9s² +(6/5)s*h . . . . . . . the formula for the modified area (in terms of original dimensions)
_____
Of course, in terms of the modified dimensions, the formula is the same:
.. S' = s'(s' +2h')
The correct first step in finding the area of a base of a cylinder is to find the length of radius of the circular base.
