You would need to find the circumstance which the formula is pi*D. with D being the diameter. you would multiply 14 by 3.14 and get 43.96. Therefore the circumstance would be 43.96. hope this helped

Since it is round, it is a circle.

Distance round a circle is the perimeter. Perimeter of a circle is = πd

where d = diameter.

Perimeter =  πd =  π*14 = <span> 14π

Perimeter </span>≈ 14 * 3.14159 ≈ 43.98226

Distance around the patio ≈ 43.98 m.

How many triangles can be constructed with angles measuring 80° 80° and 40°
Dmitriy789 [7]
None because a triangle has to equal 180 degrees and the measurements you have equal 200 degrees. So no triangles can be constructed with those measurements

How do you solve 23=-7-5x
melomori [17]

23=−7−5x

23=−5x−7

−5x−7=23

−5x−7+7=23+7

−5x=30

(−5x/−5)=(30/−5)

x=−6

P(A)=0.22 and P(B)=0.46 <br> Find P(A OR B)
morpeh [17]

In general, the probability of a disjunction is

P(A \lor B) = P(A)+P(B)-P(A\cap B)

In this case, A and B are mutually exclusive, so P(A\cap B)=0

This simplifies the formula to

P(A \lor B) = P(A)+P(B) = 0.22+0.46 = 0.68

Line with a slope 6 passes through the points (2,-10) and (5,g)
Irina-Kira [14]

Answer:

8 =g

Step-by-step explanation:

We have two points so we can use the slope formula

m = ( y2 -y1)/(x2-x1)

6 = ( g - -10)/(5-2)

6 = (g+10)/(5-2)

6 = (g+10)/3

Multiply each side by 3

6*3 = g+10

18 = g+10

Subtract 10

18-10 =g

8 =g
