Answer:

276.46 in²

Step-by-step explanation:

Surface area of the hemisphere

= 2π(4)²

= 32π in²

Lateral Surface of the cone

= 2π(4)(5)

= 40π in²

Surface area of the base

= π(4)²

= 16π in²

Total surface area

= 32π + 40π + 16π  

= 276.46 in²

Answer:

The equation is y = x + 9.

Step-by-step explanation:

We need to equation of SR

Slope = slope of UV = 3/2

= 1.

One point on SR is (-2, 7) so using the point-slope form of the equation:

y - y1 = m(x - x1)

Here m = 1, x1 = -2, y1 = 7:

y - 7 = 1(x - (-2))

y - 7 = x + 2

y = x + 9

Which expression is represented by the diagram? ( Marked 1-4, I can't paste the question.)
wel

Answer:

-6-(-1)

Step-by-step explanation:

Since all the boxes are negative, and there are 6 boxes, the first part of the equation is -6.  Then since the last box is being taken away, we are subtracting it.  The last box is still negative though so the last part is -1.  Since -6 subtracted by -1 is -6-(-1), the answer is:

-6-(-1)
