Work out the perimeter of a quarter- circle with radius 7cm.

Perimeter = radius + radius + 1/4 circumference

                 = 7 + 7 + (2 x 22/7 x 7)/4

                 = 7 + 7 + 44/4

                 = 7 + 7 + 11

                 = 25 cm

5.5 cm

Step-by-step explanation:

answer: b.36 feet

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
