You can estimate a tree's age in years by using the formula r a = where r is the tree's radius without bark and w is the average thickness of the tree's rings. The circumference of a white oak tree is 100 inches. The bark is 0.5 in. thick, and the average thickness of a ring is 0.2 in. Estimate the tree's age and the area enclosed by the outer circumference of the widest ring. Round answers to the nearest tenth. The age of the tree is about |years. The area enclosed by the outer circumference of the widest ring is in?.
