To find the volume of a cylinder, start with the formula for the volume of a cylinder.
Volume =
Notice that our cylinder has a radius of 7 and a height of 16. So we have
() (7) (16)
Let's start by simplifying the exponents. ≈ 49
() (49) (16)
49 × 16 = 784
We can add a unit so we have 784.
Answer:
area = 16.56
P=18.6
Step-by-step explanation:
Area= L*W
Perimeter = L+L+W+W
The length of each of the equal sides of an isosceles triangle are 80.
Explanation:
Given that the forest clearing is in the shape of an isosceles triangle with a base of 75 feet.
The perimeter of the forest clearing is 235 feet.
We need to determine the length of each of the two equal sides.
Length of the two sides.
Let x denote the length of each of the equal sides.
The value of x can be determined using the perimeter formula.
Perimeter of the triangle = Sum of all the three sides of the triangle.
Thus, we have;
Thus, the value of x is 80.
Hence, the length of each of the equal sides of an isosceles triangle are 80.
Y+2x=24
product is max
xy=max
we have
y+2x=24
minus 2x both sides
y=24-2x
sub that for y in xy=max
(24-2x)(x)=max
-2x^2+24x=max
we have a parabola opening down
the coordinates of the vertex is our answer
the x value of the vertex is -b/2a where
ax^2+bx+c=y
-24/2(-2)=-24/-4=6
xvalue=6
we can just sub
y=24-2x
y=24-2(6)
y=24-12
y=12
the numbers are 6 and 12
the product is 72
the numbers are 6 and 12
