Answer:

Step-by-step explanation:

These triangles are similar triangles, so there is a number that you can multiply the sides of TUV to find the side lengths of QRS. looking at the triangle, the similar sides are RS being similar to UV and RQ being similar to UT.

If RS~UV, then there is a ratio between them. 54/36=1.5. The ratio is 1.5.

RQ~UT, and by a factor of 1.5, so divide RQ by the scale factor. 24/1.5=16. UT=16=x+5.

x+5=16, subtract 5 from both sides.

x=11

Find the area of a circle with radius 5mm, rounded to the nearest tenth. A. 15.7mm2 B. 31.4mm2 C. 78.5mm2 D. 246.7mm2
icang [17]
1. The Formula to getting the area of a circle is pi r^2= 3.14 times the radius squared. Plug in the number given in the question to get your answer.
2. The Circumference formula is 2pir which is 2 time 3.14 times the radius given. Plug in the number to get your answer.
3. This one is giving you the diameter, therefore you need to divide the diameter by 2 to get the radius (diameter is twice the size of radius) and plug in the radius into the first formula (3.14 times r^2) to get your answer.

Find the total surface area of this cone. Round to the nearest tenth.
leva [86]

Step-by-step explanation:

for given cone:

h = 3 ft, r = 3 ft

Let l be the Slant height of cone.

\therefore \: l =  \sqrt{ {h}^{2}  +  {r}^{2} }  \\  =  \sqrt{ {3}^{2} +  {3}^{2}  }  \\  =  \sqrt{9 + 9}  \\  =  \sqrt{2 \times 9}  \\   \therefore \: l= 3 \sqrt{2}  \: ft \\  \\ total \: surface \: area \: of \: cone \\  = \pi \: r(l + r) \\  = 3.14 \times 3(3 \sqrt{2}  + 3) \\  = 9.42 \times 3( \sqrt{2}  + 1) \\  = 28.26 \times (1.414 + 1) \\  = 28.26 \times 2.414 \\  = 68.21964 \\  \approx \: 68.2 \:  {ft}^{2}
