Calculate the center angle a if the lenght of the circular arc 31,4cm and the radius of the circle 9cm

3.48 radian

Step-by-step explanation:

length of arc= radius * center angle

31.4 = 9 * angle

angle is in radian

false

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
