Answer: Let x = the length of a side of the square
a2 + b2 = c2
x2 + x2 = 102
2x2 = 100
x2 = 50
x = √50
x = 5√2 cm
Step-by-step explanation:
The least possible height is the height of the cylinder when the volume is 324π cubic inches. To determine that height, we use the formula for the volume of a cylinder. We do as follows:
Volume = πr^2h
324π = π(6)^2(h)
h = 9 inches
The answer is 6%.

Answer:
Step-by-step explanation:
height(h) mid value frequency
in cm x f xf
120<t≤124 122 7 854
124<t≤128 126 8 1008
128<t≤132 130 13 1690
132<t≤136 134 9 1206
136<t≤140 138 3 414
total 40 5172
mean height=5172÷40=129.30
mean height=129.30 cm
b.
it is an estimate i have taken only mid value,for example in the interval all the 7 students may be of length greater than 122 and viceverse.
Similarly for other intervals.
