You visit the oldest tree in the world, Methuselah, and want to know how old it actually is. You estimate the diameter including the bark to be 87 inches. The bark is approximately 1.5 inches thick. The width between each tree ring is 0.00865 inches. Using a=r/w where a is the age, r is the radius of the tree without bark, and w is the width between each ring; find the age, cross-sectional area, and circumference of the tree. (Area and circumference not including bark) Round to nearest whole number for all answers
Age= 4855 years
Area= 5542 inches2
Circumference= 264 inches
