no, try doing the calculations without 3.14 and use pi instead

i really dont know i did and i got 753.98223687 this time

when you find the area using \[ \pi r^2\] leave pi in. do not use 3.14 you get \[ 36 \pi\]

i dont have my graphing calc right now so im using a scientific one right now

V= 1/3 pi r^2 h if you leave the pi to one side: \[ \pi (\frac{1}{3} 36 \cdot h )\] just figure out the stuff in the parens

I got B for this is that right? Find the volume of a square pyramid with base edges 4 ft. and height 15 ft. Choose one answer. a. 20 cu. ft b. 80 cu. ft c. 240 cu. ft d. 60 cu. ft

the answer is \[ 240 \cdot \pi \] 240 times pi if you replace pi with 3.14159... you get 753. with lots of decimals people just write it 240 pi and if someone wants the exact number, they can multiply it out themselves.
