The surface area is 248 square inches
Step-by-step explanation:
The missing dimensions (that complete the question) are:
--- L
---- W
--- H
Required:
Calculate the surface area
The surface area is:
Substitute values for L, W and H
Remove bracket
Answer:
Step-by-step explanation:
5.25+6.75+7.75=
12+7.75=19.75
b->19.75
Volume of a cone is
(pi*r^2)*h/3
The radius is 50/2 = 25
To find h, we need to use the pythagorean theorem with the slant edge.
a^2 + b^2 = c^2
a^2 + 25^2 = 50^2
a^2 = 1875
a = 43.301 m
pi*25^2*43.301/3 = <span>28340.44 m^3
</span>
1 m^3 = 1000 L
28340.44 m^3 * 1000L = 28,340,440 L
400 L/s
28,340,440L / 400L = 70,851.1 seconds.
70,851.1 / 60 = 1,180.9 minutes.
I think this is right?
Answer:
C.
Step-by-step explanation:
x= 4, y = 12
A . y = 6x
12 = 6*4
12 = 24 false
C. y = 3x
12 = 3*4
12 = 12 true
