Acylindrical rainwater tank is 1.5 m tall with a diameter of 1.4 m. what is the maximum volume of rainwater it can hold? ? i need answer..

The maximum volume of rainwater will be "2.3 m³".

Given values are:

Height = 1.5 m

Diameter = 1.4 m

The Area of circle will be:

=

=

=

hence,

The volume of cylinder be:

=

=

Thus the answer above is correct.

To work out the volume of a prism, you multiply the area of cross-section by the height (or length).

So for a cylinder, you work out the area of the circle and then multiply it by the height.

Area of circle (or cross-section) = π × radius²

                                                = π × 0.7²

                                                = 0.49π   m²

Now to get the volume of the cylinder, you times this area of the cross-section by the height of the cylinder:

Volume = 0.49π × 1.5

            = 2.3 m³  (accurate to 2 decimal places)

The maximum volume of rainwater the cylinder can hold is:

2.3 m³

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
