Answer:

#1. 31.4 square units

Step-by-step explanation:

We are solving for the square units and also we are circumference formular

which is C = R x 2) (3.14)

R is 5 but in a case they don't give us the Radius and gives us the Diameter we decide the Diameter by 2 and we will get the radius.

Back to the problem

C = R x 2) (3.14)

C =  5 x 2 x 3.14

C = 10 x 3.14

C = 31.4
