10) V=πr² *h= π*10²*12≈3770
11) V=A(base)*h= (3√3/2)*(9²)*10=2104
A(base)=(P*a)/2=(6*9*3√3)/2=9*9*3√3/2
12)V=πr² *h=π*18² *6≈6107
13)V=4*3*12=144
14) h(triangle)=√(5²-3²)=√16=4
A(base)=(3*4)/2=6
V=A(base)* height (prism)=6*2=12
15) V=A(base)*h= (3√3/2)*(6²)*11= 1029
16)V=A(base)*h=2(1+√2)5²*22≈2656
A.) Never
the sum is always irrational
Answer: 12.263 sqm
Step-by-step explanation:
1 square meter = 10.7639 square feet
132 square feet in meters would therefore be;
1 sqm : 10.7639 sqf
x sqm: 132 sqf
10.7639x sqm = 132sqf
x sqm = 132 / 10.7639
= 12.263 sqm
Answer:
5
Step-by-step explanation:
