Answer:
equal to
Step-by-step explanation:
To find the surface area of a cone, use this formula.
pi (r) (r + [square root of h^2 plus r^2] ) substitute
h = height = 22 r = radius = 28/2 = 14 [ ] = sq. root
pi (14) (14 + [ 22^2 + 14^2 ]) solve exponents
pi (14) (14 + [484 + 196]) add
pi (14) (14 + [680]) solve square root
pi (14) (14 + 2[170]) add
pi (14) (40.0768) multiply
pi (561.075) is about 561.1 rounded to nearest tenth
So the answer is C. 561.1pi cm^2
Answer:
Step-by-step explanation:
M' = (8,2)
A' = (7,6)
T' = (2,6)
H' =(3,2)
If this is a reflection across the y axis, then all that will change is the x value. You have to read that carefully to make sure you understand it.
Notice that T = (-2,6). All that happens is the the minus becomes a plus.
