The formula for volume of a cylinder is V = pi r^2 h. You put the numbers into the formula, and you get 25.13. So the volume of the cylinder is 25.13. The formula for volume of a cone is V = pi r^2 h/3. You put the numbers into the formula, and you get 12.57. The volume of the cone is 12.57. Then, you add the volumes of the two shapes together. 25.13 + 12.57 = 37.7. You have to round it to the nearest whole number, so since 7 is greater than 5, you round up to 38. 38 mm is the answer.

Write a formula for fogoh, where f(x) = x + 1, g(x) = - 3x, and h(x) = 5 - X.<br> (fogoh)(x) =

Marina86 [1]

Step-by-step explanation:

f(x) = x + 1

g(x) = -3x

h(x) = 5-x

find fogoh

first we find fog

f(g(x)) = -3x + 1

then we find fogoh = -3(5-x ) +1

= -15 + 3x +1

= 3x -14

Triangle TRI has a base of m centimeters and a height of n centimeters. Rectangle RECT has a length of n centimeters and a width

hram777 [196]

The area of the triangle is
a=( m x n) /2 in cm² , implies 2xa = m xn
the area of the rectanglle
A= n x m in cm²
but we know <span> 2xa = m xn = A, </span>
that means the surface of the rectangle is 2 times of the area of the triangle
