The next event requires each runner to jump 8 hurdles that are spaced 12. 3 meters apart. If there are 15 meters from the starting line to the first hurdle and 10. 5 meters from the last hurdle to the finish line, how long is the race? Show your work.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

i dont know

step-by-step explanation:

umm. i dont know

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
