When you add 7 and 8 it equals 15 so if you were to add 17 and 18 it would become 35 because that extra ten from the 7 and 8 can equal a ten which is moved over to the tens place. Like if you did 12+29 you do the ones. then the last number from the 11 (1) goes in the ones and you move the first one over do the tens which equals 3 + 1 in the tens so it equals 41.
Does the question have any answers, I can’t really go off of just that
Answer:
A = 64 pi
Step-by-step explanation:
The circumference can be found by
C = 2 * pi *r
16 pi = 2 * pi *r
Divide each side by 2 pi
16 pi/ 2 pi = 2 * pi *r/ 2 pi
8 =r
The radius is 8
To find the area
A = pi r^2
A - pi (8)^2
A = 64 pi
