Answer:

LA=πrs

Surface Area=πrs+πr²

Step-by-step explanation:

We are given the slant height(s) and the radius(r) of the cone.

We have to find the formula for Lateral Area(LA) of the cone and surface area of cone.

Lateral Area of cone is given by: πrl

where r is the radius and l is the slant height

Here l=s

Hence, Lateral Area(LA)= πrs

Surface area of cone= lateral area of cone+area of base

                                  = πrs+πr²

The total Surface Area of a right Cone is the sum of the area of its base and the lateral (side) surface.

The formula for the total surface area of a right cone is T.S.A=\pi rl+\pi r^2

Where r is the radius, and l is the slant height

brainly hdd and ram memory both tests both come back with positive old tower pc doesn't always turn on and randomly
mash [69]

The correct option is 4. PSU.

The hardware part that would be checked next is PSU.

<h3>What is Power Supply Unit PSU?</h3>

An internal piece of IT hardware is known as a power supply unit (PSU). Despite their name, power conversion devices, or PSUs, do not really supply power to systems.

Some key features of PSU are-

  • A power supply specifically transforms alternating high voltage current (AC) to direct current (DC) and regulates the DC output voltage to the precise tolerances needed for contemporary computing components.
  • There is, however, a PSU substitute that may be utilized in specific circumstances.
  • Electrical power can be transported inside network cables using Power over Ethernet (PoE), freeing the device from being bound to an outlet.
  • Because PoE can deliver wireless access points wherever it is most convenient and uses less room for wiring, it is perfect for systems that need greater flexibility.

Katrina drinks 0.5 gallons of water per day which expression shows how to find the number of cups of water she drinks in a week
kobusy [5.1K]

Answer:

56 cups of water

Step-by-step explanation:

Katrina drinks 0.5 gallons of water per day

We have 7 days in a week, hence, the number of gallons of water she drinks per week is calculated as:

1 day = 0.5 gallons

7 days = x

Cross Multiply

1 day × x = 7 days × 0.5 gallons

x = 7 days × 0.5 gallons/1 day

x = 3.5 gallons

Note that 16 cups = 1 gallon

The number of cups of water she drinks per week is

1 gallon = 16 cups

3.5 gallons = x

Cross Multiply

1 gallons × x = 3.5 gallons × 16 cups

x = 3.5 gallons × 16 cups/1 gallons

x = 56 cups

Therefore, Katrina drinks 56 cups of water in a week

A blue jay lives in a nest that is 12 meters high in a tree the blue jay flies 15 meters to get from its nest to a flower on the
Ivan

Answer:

The distance between the base of the tree and the flower is 9m

Step-by-step explanation:

Here, we have to paint a picture.

The flower is on the ground, the height of the tree is 12m.

The distance from the nest to the flower on the floor is 15m

Indisputably, what we have is a right angled triangle, with the height being 12m, the length of the hypotenuse being 15 and we are asked to calculate the adjacent which represents the distance from the base of the tree to the flower

To get this distance, we simply apply the Pythagoras’ theorem which states that the square of the hypotenuse(longest side of the triangle) is equal to the sum of the squares of the other two sides.

Thus mathematically, we know that our hypotenuse is 15m and the height is 12m

The length we are to calculate is the adjacent and it is equal to;

15^2 - 12^2

= 225 - 144

= 81

The length is thus

√(81) = 9m

Please check attachment for a diagrammatic picture of the triangle
