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

<em>See attachment</em>

<em></em>

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.

<em>Hence, the surface area is 1300 square inch</em>

(the dimensions are shown in the picture)
Oksanka [162]

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.
