Answer:

1) 81.64 ft      2) 12.56 in

Step-by-step explanation:

a radius is a line <em>halfway</em> through the circle starting in the middle... a diameter is double that, or a line that goes <em>all the way </em>through the circle

you are working with diameter

in order to find the circumference of a circle using diameter, the equation is

C (circumference) = pi x d (diameter)

in order to find the circumference of a circle using radius, the equation is

C = 2 x pi x R (radius)

If the product of two number is 10 and the sum is 7 ,then the longest of the two number is​
irinina [24]

Answer:

5 units

Step-by-step explanation:

Step one:

Given data

Le the first number be x

and the second number be y

So

x*y= 10-----------------1

and

x+y= 7-----------------2

from eqn 1

x= 10/y

put x= 10/y in eqn 2

10/y+y= 7\\\\10/y= 7-y

cross multiply we have

10=y(7-y)\\\\10=7y-y^2

rearrange

y^2-7y+10=0

the factors of the quadratic expression are

-5 and -2

y^2-5y-2y+10= 0\\\\y(y-5)-2(y-5) =0\\\\y-2=0\\\\y= 2\\\\y-5= 0\\\\y=5\\\\

The longest side is 5 units

8 miles in 0.5 hour what rate in miles per hour
yan [13]
In this question it is already given that a person travels 8 miles in 0.5 hours. This is enough information to get to the required answer. Let us first write down all the information's that are already given in the question.
In 0.5 hours the person covers a distance = 8 miles
Then
In 1 hour the person covers a distance of = 8/0.5 miles
                                                                   = 16 miles
So the speed of the person in miles per hour = 16/1 miles/hour
                                                                         = 16 miles per hour

You are inscribing a regular hexagon in a circle. You need to know the angle measure between the vertices. You divide 360° by wh
Svet_ta [14]

To know the angle measure between the vertices, you divide 360° by 3. Option C

<h3>Interior angles of a hexagon</h3>

Formula for interior angles of polygon is given as;

= ( n -2 ) × 180 degrees

Hexagon has 6 sides, n = 6

= ( 6 - 2 ) × 180° = 4 × 180° = 720°

Each interior angle = 720/ 6 = 120

To get 120 from 360

= \frac{360}{120}

= 3

Thus, to know the angle measure between the vertices, you divide 360° by 3. Option C
