The answer to this problem

Ksivusya [100]

Answer:

B. $\frac{7\sqrt{2}}{34}$

Step-by-step explanation:

Cos θ = Adjacent/hypotenuse

Adjacent = 7

Hypotenuse = √(23² + 7²) = √578 = 17√2

Thus:

Cos θ = $\frac{7}{17\sqrt{2}}$

Rationalize

Cos θ = $\frac{7*\sqrt{2}}{17\sqrt{2}*\sqrt{2}}$

Cos θ = $\frac{7\sqrt{2}}{17*2}$

Cos θ = $\frac{7\sqrt{2}}{34}$

Step-by-step explanation:

Given:

Base = 22'

Height = 28'

Find:

Total area

What is the volume of corn held in this cone-shaped grain silo? Use 3.14 for π and round to the nearest cubic foot. Enter your a

MrRa [10]

Answer:

3014 cubit foot

Step-by-step explanation:

Find the diagram attached

Volume of the cone = 1/3πr²h

r is the base radius of the cone

h is the height

Given

r = 6ft

Get the height using the pythagoras theorem

h² = 10² - 6²

h² = 100 - 36

h² = 64

h = √64

h = 8ft

Get the volume

Volume = 1/3πr²h

Volume = 1/3 * 3.14 * 6^2*8

Volume = 3.14 * 12 * 8

Volume =3,014.4

Volume = 3014 cubit foot to the nearest foot
