Answer:
7m
Step-by-step explanation:
1. find ratio of small to large triangle (6:18 = 1:3 / 8:24 = 1:3)
2. find blank side of smaller triangle (if ratio is 1:3 then take the large triangle side that matches the smaller unknown side and divide by 3 to size down the line to find unknown side)
Answer = 7m
Answer:
Step-by-step explanation:
Answer:
r = √3v/π
Step-by-step explanation:
in order to make r the subject of formulae from
v = 1/3πr²
multiply through by 3
3(v) = 3 ( πr²/3)
3v = πr²
divide both sides by π
3v/π =πr²/π
3v/π= r²
in order to make r stand out we would do that by squaring both sides
r = √3v/π
