I'm doing circumference and area of circles
Directions-
Find the circumference and the area of a circle with the radius. Use pi=3.14 or 3 1/7, round to the nearest tenth. (r stands for radius, I need both area and circumference)
4. r= 16 inches
5.r= 12 yards
6.r= 11 mm
Find the AREA of each circle. use pi (3.14). Round to nearest tenh (d is diameter)
7. r=1.7 cm
8. d= 21 inches
9. r= 4.5 meters
10. d= 11 cm
11. r= 2 inch
12. d= 12 m
Find the area of the circle given the circumference (algebra)
C= 4 yrds
C= 43.96 cm
C= 12 inch
Please helppp

ill do one
4. r= 16 inches
circumference = 2πr or πd
2(3.14)(16) = 100.48
Circumference = 100.48 inches
Area = πr^2
3.14(16)(16) = 803.83
Area = 803.84 inches |

| The problem is I can't use my calculator in the dark because it's solar-powered, I'm VERY tired, on a 1gen iPod (slow) and need help badly. And no, I can't turn my lights on. |
