Answer:

(x - 1)^2 + (y - 3)^2 = 4^2

Step-by-step explanation:

The generic equation of a circle in standard form is:

(x - h)^2 + (y - k)^2 = r^2, where the center is (h, k) and the radius is r.

Taking the given info, we then have:

(x - 1)^2 + (y - 3)^2 = 4^2

How many numbers greater than 10 and smaller than 25 with distinct digits can we make by using two of the digits 2, 0, 1, and 8
saul85 [17]

Answer:

Only four numbers can be formed

Step-by-step explanation:

We are to make numbers greater than 10 and less than 25

Distinct digits should be there

As such all numbers lying between 10 and 25 are

11,12,.....24

Of these the conditions are only 2, 0, 1 , 8 should be used.

First digit cannot be 0 or  8 because we want two digit numbers between 10 and 25

So first digit can be either 1 or 2

If first digit is 1, second digit can be either 2 or 8 i.e. only 12, 18

If first digit is 2, second digit can be 0 or 1 cannot be 8 i.e. only 20 , 21

Only 4 numbers can be formed

Item 16

Answer:

Step-by-step explanation:

Given that the dresser is in shape of a rectangular prism

Note that, a rectangular prism has a shape of a cuboid

So, area of the rectangular prism is same as area of a cuboid

A = (2LB + 2LH + 2BH)

Where

L is length

B is breadth

H is height

Then, given the dimension of the rectangular prism to be

2ft by 2ft by 6ft

Then, you can assume that,

Length L = 2ft

Breadth B = 2ft

Height H = 6ft.

NOTE: you can take you assumption anyhow, there is no standard, you will get the same answer.

Then,

A = (2LB + 2LH + 2BH)

A = (2×2×2 + 2×2×6 + 2×2×6)

A = (8 + 24 + 24)

A = 56 ft²

The total surface area of the dresser is 56ft²
