Answer:
Negative
Step-by-step explanation:
87.96 You need the height of the circle which is
14 because 7 is only the radius. And you put it into the equation and solve C=2πr
Let
Vco------------------- >Volume cone
Vcy------------------ >Volume cylinder
r= 8mm
hco----------- > height of cone=18 mm
hcy------------ > height of cylinder =54-18=36 mm
then
Vco=π*r² *hco/3--------- > π*8² *18/3=π*384 mm³
Vcy=π*r² *hcy--------- > π*8² *36=π*2304 mm³
the total cubic millimeters of sand=Vco+Vcy=π*384+π*2304=π*2688
if 10π cubic millimeters --------------------- > 1 seg
π*2688--------------------------------- X
X=π*2688/10π=268.8 seg
the answer is 268.8 seg
Answer:
3/8 , 3/6. 3/4
Tad drove the least miles because the miles ridden is less than both 3/6 and 3/4 miles
Dale rode the second greatest mile because the miles ridden is greater than 3/8 but less than 3/4
Harrison rode the greatest mile because the miles ridden is greater than both 3/6 and 3/8
Step-by-step explanation:
to order the miles ridden , convert the fraction to decimals. to do this, divide the numerator by the denominator
3/4 = 0.75
3/6 = 0.5 miles
3/8 = 0.374
7 x 1 = 7
7 x 2 = 14
7 x 3 = 21
7 x 4 = 28
7 x 5 = 35
