(i.) CA = πrl
CA = π (5*13)
CA = 65π
(ii.) TA = πrl + πr^2
TA = 65π + π (5^2)
TA = 65π + 25π
TA = 90π
(iii.) To get the height of the cone, you have to use the Pythagorean theorem. Plug in the radius for a and the slant height for c.
a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169 Height = 12
b^2 = 144
b = 12
(iv.) v = (1/3)πr^2h
v = (1/3)π(5^2)*12
v = (1/3)π(25*12)
v = (1/3)π*300
v = 100π
Answer: =0 + 5n
Step-by-step explanation:
A= h•w
6+2 = 8 feet long
4.5+1.5= 6 feet wide
8*6= 48 ft
Answer: 48 feet

In the slope intercept form equation, y =mx+b, m is the slope, or the coefficient of x.
Therefore, the slope, or m, in this situation is -2/3.
Hope this helps!
