Answer: 4-x^2
explanation:
Divide the equation by 4. 16 divided by 4 is 4. and -4x^2 divided by 4 is -x^2.
Answer:
length = 27
breadth = 16
Step-by-step explanation:
The equation to determine the perimeter of the rectangle is given as
6x-10=86
the solution to above is x=16
Hence one of the side is 16. The formula for perimeter is given as
P=2(l+b)
if b=x =16
and P=86
replacing them inthe formula for perimeter
86=2(l+16)
dividing both sides by 2 we get
43=16+l
subtracting 16 from both sides we get
27=l
Hence the length and breadth of the rectangle are 27 and 16 respectively
Answer:
138.16 square feet
Step-by-step explanation:
The surface area of the cylinder consists of one rectangle and two circles.
1. The radius of the circle is 4 ft, then the area of the circle is
2. The width of the rectangle is 1.5 ft, the length of the rectangle is the circumference of the circle.
Find the circumference:
Hence,
3. The surface area of the cylinder is
