Answer:
f(3) = 22
Step-by-step explanation:
f(x) = 2x^2 + 4, find f(3)
f(3) = 2(3)^2 + 4
f(3) = 2 (9) + 4
f(3) = 18 + 4
f(3) = 22
Answer:
total SA = 622.725mm^2
Step-by-step explanation:
we are trying to find the surface area of this structure
we can start by breaking this structure into three pieces.
(surface area of the left hemisphere)+(surface area of the right hemisphere)+(surface area of the right cylinder inbetween those 2 hemispheres)
1. surface area of the hemisphere.
surface area of a hemisphere is 4
d = 8.4mm so r = 4.2mm.
surface area =
we need to take the half of 221.607 since it is half the hemisphere which is 221.670/2 = 110.835mm^2
we have two half hemisphere on the left and right so the tottal surface area of both the half hemisphere is 110.835x2 = 221.670mm^2
2. surface area of the right cylinder.
SA of right cylinder =
So the entire surface area is.
(surface area of both the half hemisphere + surface area of the right cylinder)
221.607+401.118 = 622.725mm^2
1. m + (m/2) = 200
2. g + 5 = 40
The square root of 324x² is equal to 18x.
Look at the signs and turn it into an easier form:
35 - 13 + 8 + 6
= 36
