Answer:
37.5
Step-by-step explanation:
360-125-(35×2)-90= 75
75÷2=x
x= 37.5
Answer:
12/5=x and -3=n
Step-by-step explanation:
11) x-10-3x-4=7x-5
2x-14=7x-2
-12=5x
12/5=x
12)-6n-20=-2n+4-12n
-6n-20= -14n +4
-24=8n
-3=n
Answer:
42 pi
Step-by-step explanation:
The area of the base is the area of a circle
A = pi r^2
A = pi (3)^2 = 9pi in^2
The circumference is
C = 2*pi*r
C = 2*pi*3 = 6pi
The lateral surface area is
lsa = C * h = 6pi *4 = 24 pi
SA = 2 bases + lsa
2 * 9pi + 24 pi
18pi+24 pi
42 pi
