Answer:
Surface Area = 283
Step-by-step explanation:
Radius = 3
Height = 12
Formula for suface area is SA= 2πrh+2πr^2
let "r" be for radius
let "h" be for height
SA=2*π*3*12+2*π*3^2
SA=282.74
round to the nearest ones spot and that will make the surface area = 283
Answer:
5ft
Step-by-step explanation:
perimeter=l+l+w+w
l=12
p=24+2w
34-24=10
10/2=5
Let's solve for x first,
3x + 5y - 5y = 1 - 5y
3x/3 = 1/3 - 5y/3
x = 1/3 - 5/3y
Let's now plug that into the other equation,
7(1/3 - 5/3y) + 4y = -13
7/3 - 35/3y + 4y = -13
7/3 - 7 2/3y - 7/3 = -13 - 7/3
- 7 2/3y (-3/23) = -15 1/3 (-3/23)
y = 2
The answer is 2
Answer:
79,200
Step-by-step explanation:
There are 5280 feet in 1 mile, then you just multiply 5280 by the number of miles (15). So 5280 x 15 = 79,200
