The largest tree in the world is the General Sherman sequoia in Sequoia National Park, California. It is 275 feet high, has a diameter of 36.5 feet, and has an estimated weight of 2,150 tons. Fin the sequoia's circumference to the nearest tenth of a foot. Use 3.14

C = pi * d

I don't understand the part of "nearest tenth of a foot". My answer is 114.61 but I don't get the part above mentioned.

Rounding it to the nearest tenth is 114.6
The first place after the decimal point is the tenths place.
