Find the surface area.

Answers

Answer 1

Answer:

1120

Step-by-step explanation:

area of triangle= 1/2★base★height

area of traingle =1/2★15★8=60

area of 2 triangle= 60+60=120

area of base rectangle= length ★breath

=15★25=375

area of slanting rectangle= 25★17=425

area of side rectangle=8★25=200

so total area= 120+375+425+200=1120

Step-by-step explanation:

s= 550km

v = 100km/hr

t = ?

SPEED = DISTANCE/ TIME TAKEN

or, v = s/t

or, 100km/hr = 550km/ t

or, t = 550/100

t = 5.5

t = 5 hrs 30 minutes

8:42

+5:30

It will take 2800 tiles to cover the entryway.

If a 12-sided fair die is rolled twice, find the probability that both rolls have a result of 8.

Answers

Answer:

1 in 144

Step-by-step explanation:

There is one 8 on a 12-sided die, so the probability of rolling an 8 once is [tex]\frac{1}{12}[/tex].

We are rolling twice, so [tex](\frac{1}{12})^{2} =\frac{1}{144}[/tex].

Owen and Ethan have $175 together. How much money does each of them have if Ethan has $33 more than Owen.

Owen has $
Ethan has $

Answers

Answer:

Owen has $71 and Ethan has $104

Step-by-step explanation:

Create a system of equations where o is how much money Owen has, and e is how much Ethan has

x + e = 175

e = x + 33

Solve by substitution by plugging in o + 33 in as e, in the first equation

o + e = 175

o + (o + 33) = 175

2o + 33 = 175

2o = 142

o = 71

So, Owen has $71 dollars

To find how much Ethan has, add 33 to this, since he has $33 more than Owen

71 + 33

= 104

So, Owen has $71 and Ethan has $104

What is the volume of a cylinder with base radius 2 and height 5?
Either enter an exact answer in terms of 3.14 for pi

Answers

Answer:

V ≈ 62.83

Step-by-step explanation:

Cylinder Formulas in terms of r and h

Calculate the volume of a cylinder:

V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside):

L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles):

T = B = πr2

Total surface area of a closed cylinder is:

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Solution

V=πr 2h = π · 22 · 5 ≈ 62.83185

Therefore, the volume of the cylinder in the nearest tenths is V ≈ 62.83

Hello i need help please

Answers

Answer:

radius = 5 cm

height = 10 cm

Volume = 261.8 cm³

Step-by-step explanation:

Radius (r) = 5 cm

Height (h) = 10 cm

Volume of the cone (V) = ⅓πr²h

Plug in the values

V = ⅓*π*5²*10

V = ⅓*π*25*10

V = 261.8 cm³ (nearest tenth)
