Answer:
245 cm²
Step-by-step explanation:
The surface area of a cone is given by ...
SA = πr(r +s) . . . . where r is the radius, and s is the slant height
Filling in the given values, we have ...
SA = (3.14)(3 cm)(3 cm +23 cm) = (3.14)(3)(26) cm² ≈ 245 cm²
The surface area of the cone is about 245 cm².
1 kg = 2.20462 lbs
so 2.7 kg = 2.7(2.20462) = 5.952474....rounds to 5.95 lbs
The first one is a maximum and the a.s. is x=1
The second one is a minimum and the a.s. is x=-2
Combine like terms you would get 4c=48 then divide it by 4 you'll get c=12
X+23=-22
-23 -23
x=-45
a+(-1.3)=-4.5
or
a-1.3+-4.5
+1.3 +1.3
a=3.2
