Question 1 - the first choice is right
Question 2- the first choice also
Answer:
78.5 units
Step-by-step explanation:
To find the area of a circle the formula is πr"2"
First we have to find the diameter the find the radius. We already know that the circumference is 31.4 what we have to do now is work backwards. ( 31.4 / 3.14=10) If the diameter of a circle is 10 the radius is 5. now we just have to follow πr"2" to find the area of a circle. (5"2"= 25 x 3.14= 78.5 units)
