---------------------------------------------- Find Volume of 1 tennis ball: ---------------------------------------------- Volume of 1 tennis ball = 4/3 x 3.14 x (2.5 ÷ 2)³
Volume of 1 tennis ball = 8.18 in³
---------------------------------------------- Find Volume of 3 tennis balls: ---------------------------------------------- Volume of 3 tennis balls = 8.18 x 3 = 24.54 in³
---------------------------------------------- Find Volume of teh cylindrical canister: ---------------------------------------------- Volume of the cylindrical canister = 3.14 x 1.5² x (2.5 x 3)
Ask her why she is crying. If she explains why, listen and comfort her. If she says to "go away" or "i don't want to talk about it," give her space and come back later. She needs to let it out, so have patience :)
