Question

Plants The world's largest flower, the Giant Raffesia is 91 centemeters in diameter. Use a calculator to find the circumference of a Giant Raffesia to the nearest tenth

Answer 1

we know that
circumference=pi*D
where
D is the diameter
D=91 cm
so
pi-----> is the value of the calculator------> 3.1415926535897932
circumference=pi*91------> 285.88 cm------> 285.9 cm

the answer is
285.9 cm
