Answer:

57 cm²

Step-by-step explanation:

Surface area of the yellow prism = front + back + right + left + top

✔️Area of the front = L * W

L = 4 cm

W = 3 cm

Area of the front = 4*3 = 12 cm²

✔️Area of the back = L * W

L = 4 cm

W = 3 cm

Area of the back = 4*3 = 12 cm²

✔️Area of the right face = L * W

L = 4 cm

W = 3 cm

Area of the right face = 4*3 = 12 cm²

✔️Area of the left face = L * W

L = 4 cm

W = 3 cm

Area of the left face = 4*3 = 12 cm²

✔️Area of the top = L * W

L = 3 cm

W = 3 cm

Area of the top = 3*3 = 9 cm²

✅Total = 12 + 12 + 12 + 12 + 9 = 57 cm²

Find he measure of Angle A

Yuliya22 [10]

Answer:

Step-by-step explanation:

I'm not really sure if this correct its just a guess but here goes.

So as 26x+5 is a vertically opposite angle. So the top angle would be 25x+5.

then we know angles in a triangle add up to 180 degrees so we would add all the angles together. 26x+5+6x-5+20=180. 26x+6x=32x. -5+5=0. 32x+20=180

180-20=160

140/32=5

6×5=30

30-5=25 so angle A is 25?

Please let me know if this is correct and if its not I'm sorry.

A cone with radius 333 units is shown below. Its volume is 575757 cubic units. Find the height of the cone. Use 3.143.143, point

STatiana [176]

Answer: 6.05 units

Step-by-step explanation:

<em>Correct question is:</em>

<em>A cone with radius 3 units is shown below. Its volume is 57 cubic units. Find the height of the cone. Use 3.14 for pi and round your final answer to the nearest hundredth.</em>

Hi, to answer this question we have to apply the next formula:

Volume of a cone = 1/3 x π x radius^2 x height

Replacing with the values given:

57 = 1/3x 3.14 x (3)^2 (h)

Solving for h

57 = 1/3 x 3.14 x 9 (h)

57 =9.42h

57/9.42 =h

h= 6.05 units

Feel free to ask for more if needed or if you did not understand something.

Hello please help me with this I need an answer immediately thank you so much see image

For this case, we know that:

$PA = PB$

Then, by Pythagorean theorem (right triangle on the right) we have:

$CP ^ 2 = CB ^ 2-PB ^ 2$

So, again using the Pythagorean theorem (right triangle on the left) we have:

$CA ^ 2 = CP ^ 2 + PB ^ 2$

Substituting values:

$CA ^ 2 = (CB ^ 2-PB ^ 2) + PB ^ 2$

Rewriting:

$CA ^ 2 = CB ^ 2$

$CA = CB$

$CA = 15$

Answer:

The value of CA is given by:

$CA = 15$
