Answer:
100.48 units³
Step-by-step explanation:
Volume of Cylinder: V = πr²h
- volume = pi × radius² × height
V = 3.14 × 2² × 8
V = 100.48 units³
Answer:
Step-by-step explanation:
there are two ways to solve systems of equations, elimination or substitution, this looks like elimination would work quickly
x= 25 -y
x + y = 25 (eq 1)
5x + y = 10 (eq 2)
subtract 2 from 1
x + y = 25
-(5x + y = 10)
-4x + 0y = 15
-4x = 15
x = - 15/4
now plug in x into either starting equations and solve for y
-15/4 + y = 25
y = 25 + 15/4
y = 100/4 + 15 /4
y = 115 /4
y = 28 3/4
we have solved it :)
Answer:
Length = 16 m , width = 10 m
Step-by-step explanation:
Let the Length of the rectangle be L meters.
Now, Width of the rectangle is (L-6) m.
Perimeter of the Rectangle = 52 m
Now, we know that
Perimeter of the Rectangle = 2(L+W)
⇒ 2(L+W) = 52 m
or, 2(L + (L-6)) = 52 m
Simplifying, we get 2L + 2L -12 = 52
or, 4L = 64
or, L = 16 m
So, width = L- 6 = (16-6) m = 10 m
So, length = 16 m
and width = 10 m
The answer is 6.2 repeating decimal.
Use a squared + b squared = c squared
60x60=3600
30x30=900
3600+900=3660
Square root 3660
=60.49
Rounded is 60 inches
