The figure shows a map of five streets that meet at Concord Circle. The measure of the angle formed by Melville Road and Emerson
Dovator [93]

Alright, lets get started.

Please refer the diagram I have attached.

The angle between Melville Road and Emerson Avenue is 119°.

Hawthorne Lane bisects the angle formed by Melville Road and Emerson Avenue.

So, angle between Hawthorne Lane and Emerson Avenue will be = \frac{1}{2} * 119 = 59.5°

Now, angle between Emerson Avenue and Thoreau Street is 135°.

Dickinson Drive bisects the angle formed by Emerson Avenue and Thoreau Street.

So, angle between Dickinson Drive and Emerson Avenue will be = \frac{1}{2} * 135 = 67.5°

So, the complete angle between Hawthorne Lane and Dickinson Drive will be = 59.5 + 67.5 = 127°

So, the answer is 127 °.   :    Answer

Hope it will help :)

What is the cross-sectional area of a cement pipe 2 in. thick with an inner diameter of 5 ft? Use pie 3.14.
Paul [167]

Answer:

1.60 ft^{2}

Step-by-step explanation:

Assuming that this is a cylindrical pipe, the area can be determined by applying the formula for calculating the area of a circle.

i.e Area = \pir^{2}

So that,

for the inner part of the pipe,

r = \frac{diameter}{2}

 = \frac{5}{2}

 = 2.5 feet

Area of the inner part of the pipe = \pir^{2}

                                 = 3.14 x (2.5)^{2}

                                 = 19.625

Are of the inner part of the pipe is 19.63 ft^{2}.

Total diameter of the pipe = 5 + 0.2

                                           = 5.2 feet

r = \frac{5.2}{2}

 = 2.6 feet

Area of the pipe = \pir^{2}

                            = 3.14 x (2.6)^{2}

                            = 21.2264

Area of the pipe is 21.23 ft^{2}.

Thus the cross sectional area = Area of the pipe - Area of the inner part of the pipe

                                           = 21.2264 - 19.625

                                           = 1.6014

The cross sectional area of the cement pipe is 1.60 ft^{2}.
