Answer:

63.5

Step-by-step explanation:

If one didn't take a 10 minute break he could drive 60 mph totalling 180 minutes but since he did and 180 - 10 = 170. He/she has to drive 180 miles in 170 min. so we take so we divde 180/170 and multiply by 60. If you round it to the nearest tenth you get 63.5

A quarter circle is attached to the side of a square as shown.
Luda [366]

Answer:

28.6 m²

Step-by-step explanation:

The measurements of the square are 4 by 4; this gives us an area of

4(4) = 16 m²

The quarter circle has a radius of 4 m.  The area of a circle is given by

A = πr².

Since we have a quarter circle, we multiply this by 1/4:

A = 1/4πr²

Using 3.14 for π and 4 for r,

A = 1/4(3.14)(4²) = 1/4(3.14)(16) = 3.14(4) = 12.56 m²

Together this gives us a total area of 16+12.56 = 28.56 m².

This rounds to 28.6 m².

<u>Area of a parallelogram:</u>

A = bh

A = 63 x 90

A = 5670

<u>Area of half-circle:</u>

A = (πr²)/2

A = (π x 27²)/2

A = (π x 729)/2

A = 729/2π

<u>Combined:</u>

5670 - 729/2π
