Sphere surface area is A=4pi*r^2. So r is sqrt(A/4pi)
r=4cm. So d=8cm

I belive it is S=2C. Even if it was three years ago, if Sherman was twice as old then, then he would be twice as old now. So you can get rid of the three years ago. if someone is twice as old, it is the same as doubling it.
Answer:
144
Step-by-step explanation:
4 triangles = 1/2 x 6 x 9 x 4 = 108
1 sq base = 6 x 6 = 36
total surface area = 36 + 108 = 144
if 3 triangles the base wouldn't be a square thus not possible to solve
Can be number 1 or number 4 I am not sure but can be 4 but take your sedición
