0T= area of the square-(15*4)
=we will get the area of circle
area of circle=pi*r(square)
here r square is not there
and area is there
so the equation will be like this
r(square)=7*the area of circle \ 22

I really need help with number 12

Usimov [2.4K]

Answer:

7.8125 gallons

Step-by-step explanation:

Because 5 gallons would cover 1600 square-foot wall so 1 gallon would cover:

1600 / 5 = 320 square-foot wall.

So to cover 2500 square foot-wall, we need in total of:

2500 / 320 = 7.8125 gallons of paint

Hope this can help you :3

The length of the hypotenuse of a right triangle is 34 inches and the length is 34 inches and the length of one of its legs is 1

nata0808 [166]

Answer:

The length of the other leg of this right angled triangle is 30 inches.

Step-by-step explanation:

We are given the following in the question:

A right angles triangle with the hypotenuse of 34 inches and the length of one of its legs is 16 inches.

Pythagoras theorem:

The sum of of square of two sides of a triangle is equal to the square of the hypotenuse.

Let x inches be the length of the other leg of this right triangle.

Thus, we can write the equation:

$x^2 + (16)^2 = (34)^2\\x^2 + 256 = 1156\\x^2 = 900\\x = 30$

Thus, the length of the other leg of this right angled triangle is 30 inches.
