Evaluate c= 2 a r, for r= 8.
c=10,
c = 16
c= 28.7
c= 16

Second Option

Step-by-step explanation:

We are evaluating aarco lengths

The formula for the arc length is:

We want to know what is the arc length for a radius of r = 8

Then we substitute r = 8 in the equation and solve

The correct answer is the second option

Correct choice is .

Step-by-step explanation:

Given equation is .

Now we need to find the value of C using given equation and .

To find that, we just need to plug into and simplify.

Hence correct choice is .

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
