I need help pls is only 1 question

Yanka [14]

Answer:

$T = 1300$

Step-by-step explanation:

Given

$Radius, r = 9\ in$

$Height, h = 14\ in$

See attachment

Required

Determine the total surface area, T

T is calculated using:

$T = 2\pi r(r + h)$

Substitute values for r and h

$T = 2\pi * 9(9 + 14)$

$T = 2\pi * 9(23)$

Remove bracket

$T = 2\pi * 9*23$

$T = 2\pi * 207$

Take $\pi = 3.14$

So, we have:

$T = 2 * 3.14 * 207$

$T = 1299.96$

$T = 1300$ --- approximated.

Hence, the surface area is 1300 square inch

Answer:

Total surface area of the prism =145.32 Square centimeters

Step-by-step explanation:

The given figure is a rectangular prism with the given dimensions of :

length(L)= 10.3 cm

Width(W)=2.2 cm

Height(H)=4 cm

Total surface area of the rectangular prism is:

$= 2(L*W+W*H+H*L)\\\\=2((10.3*2.2)+(2.2*4)+(4*10.3))\\\\=2(22.66+8.8+41.2)\\\\=2(72.66)\\\\=145.32cm^2\\\\$

Total surface area of the prism is 145.32 Square centimeters

Oliver climbed 222 meters of a steep mountain reach the summit. He then rappelled down the other side of the mountain to return

nikdorinn [45]

B -222

Because he fell/descended 222 meters. And falling or going down produces a negative integer. Also, if you were actually doing the math to try to find where Oliver is currently located, you wouldn't add 222, or 0, or subtract -444. You would subtract 222.

In addition, be aware that the question is asking you an integer to represent a situation, not the answer of where Oliver is.
