Find the total surface area of the following cone. Leave your answer in terms of pi.

12π cm^2.

Step-by-step explanation:

First work out the slant height using Pythagoras:

l^2 =  (2√3)^2 + 2^2

l^2 = 12 + 4 = 16

l = 4 cm.

Area of the base =  πr^2 =  π 2^2

Total surface area =  π* 2* 4 +  π(2)^2

= 8 π + 4 π

= 12π cm^2.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

except if the answer is in the value of money, then, it will matter. it will have to be $0.40, but i can tell this is not a money question, so .4 should be the right one.
