Find the circumference of circle when radius is 4.8yd?​

C≈30.16yd

Step-by-step explanation:

Solution

C=2πr=2·π·4.8≈30.15929yd

30.144

Step-by-step explanation:

When finding circumference for a circle the formula is diameter × pi Since we arent given the diameter we have to figure it out but the diameter is just twice the radius so 4.8 × 2 = 9.6

So 9.6 is our diameter now we just multiply this by pi so 9.6 × 3.14 = 30.144

, yes

,no

, yes

step-by-step explanation:

the given function is .

we will substitute the given points into this function to determine which points lie on its graph.

1. the first point is . we substitute and .

this gives

this implies that,

. this statement is true.

therefore lies on the graph of

2. the second point is .

we substitute this point too to obtain,

. this statement is false.

therefore the point does not lie on the graph of the function, .

3. the third point is .

we substitute this one too to get,

. this statement is also true.

this point also lies on the graph of the function
