Suppose a gas tank is in the shape of a cylinder. The tank is 20 feet long and 8 feet in diameter. Find the amount of metal used to construct the tank. (Hint: use 3.14 for pi)


A 384.5ft2
B 1028ft2
C 602.9ft2
D 1570.4ft2

Answers

Answer 1

Answer:

C. 602.9 ft²

Step-by-step explanation:

Surface area of a cylinder:

A = 2πr(h + r)

Substitute values:

A = 2(3.14)(8/2)(20 + (8/2)) = 2*3.14*4*24 = 602.88 ft²

Matching choice is C

Answers

Answer:

1st ∡ = 15.5°

2nd ∡ = 77.25°

3rd ∡ = 87.25°

Step-by-step explanation:

1st ∡:  x

2nd ∡:  y

3rd ∡:  z

Equations we can create from data given in problem:

y + z = 5x

z = 5x + 10

We have enough expressions to create an equation:

x + 5x + 5x + 10 = 180

11x = 170

x = 15.5

y = 5(15.5) = 77.25

z = y + 10 = 87.25

Answers

Answer:

288

Step-by-step explanation:

If you didnt know a triangle has the area of a square/2

so basically what im saying is the area of that square/2 equals the area of the triangle

to find the area of the square you take 24 and square it

24^2=576

finally we divide that by 2

576/2=288

so the area of the triangle is 288

The ratio of two positive numbers is 3:4. The sum
of their squares is 400. What is the sum ofthe num-
bers?​

Answers

Answer:

12 and 16.

Step-by-step explanation:

Let both positive numbers be x and y.

3/4 = x/y....... equation 1

x² + y² = 400..... equation 2

From equation 1

3/4 = x/y

Cross multiply

3y = 4x

Divide both sides by 3

y = 4x/3

Substitute y = 4x/3 into equation 2

x² + y² = 400

x² + (4x/3)² = 400

x² + 16x²/9 = 400

Multiply through by 9

9x² + 16x² = 3600

25x² = 3600

Divide both sides by 25

x² = 3600/25

x² = 144

Take the square root of both sides

x = √144

x = 12

Substitute x = 12 into equation 1

3/4 = x/y

3/4 = 12/y

Cross multiply

3y = 12 x 4

3y = 48

Divide both sides by 3

y = 48/3

y = 16
