a.) A water tank has the shape of a cone (like an ice cream cone without ice cream). The tank is
10m high and has a radius of 3m at the top. If the water is 5m deep (in the middle) what is
the surface area of the water?
b.) A kite is 100m above the ground. If there are 200m of string out what is the angle between the
string and the horizontal. (Assume that the string is perfectly straight.)
Thanks in advance
thanks just got a.) left its pretty hard been trying it for over 2 hours dunno how to find radius at halfway the cone is it simply 1.5 radius? or more complicated?
if it is 1.5 radius then pie r squared is 3.1415 times 1.5 squared which is = to 7.069 is that correct surface area for a.)?
part b is easy. using your soh cah toa rule, u can use the soh part which is sinθ=o/h where o=opposite which is 100 and h=hypotenuse which equals 200 since there is 200m of string. therefore;
i'll let you figure out the answer:P
