Answer:

We can calculate area of circle if we know the circumference

Step-by-step explanation:

Points to remember

`1). Circumference of circle = 2πr

2).  Area of circle = πr²

Where 'r' is the radius of circle

<u>Find area of circle</u>

From the above two equations we have to calculate area and circumference of a circle with radius.

If we have circumference, the we can calculate radius of the circle

r = circumference/2π

If we get radius 'r' the we can calculate area

Area of circle = πr²

<u>Answer with step-by-step explanation:</u>

We know that the formula for area of a circle is given by:

<em>Area of a circle = \pi r ^ 2</em>

So to find the area of circle, we basically need to know the radius of the circle.

If we know the circumference of the circle, we can calculate the area of the circle too.

Formula for the circumference of the circle is given by:

2\pi r

So if we know the circle's circumference, we can find the value of radius and then find the area of circle with it.

Step-by-step explanation:

To calculate the volume of a pyramid with a rectangular base, find the length and width of the base, then multiple those numbers together to determine the area of the base. Next, multiply the area of the base by the height of the pyramid. Take that result and divide it by 3 to calculate the pyramid's volume!

A cyclist travels 17 km from home to the park.
kupik [55]

Answer:

34 km/h

Step-by-step explanation:

speed = distance/time

Distance = 17km

Time = 0.5 or 1/2 hours because it's 30 minutes between 17:15 to 17:45, and 30 minutes is a half of an hour and you want km over hours

So

speed = 17/0.5

speed = 34 km/h

Area of rectangle is 2x^2+x-45

Step-by-step explanation:

Given:

Length of rectangle = 2x-9

Width of rectangle = x+5

Required:

Area of rectangle

Formula:

Area\,\,of\,\,rectangle=Length*Width

Putting values of length and width:

Area\,\,of\,\,rectangle=Length*Width\\Area\,\,of\,\,rectangle=(2x-9)(x+5)\\Area\,\,of\,\,rectangle=2x(x+5)-9(x+5)\\Area\,\,of\,\,rectangle=2x^2+10x-9x-45\\Area\,\,of\,\,rectangle=2x^2+x-45

So, Area of rectangle is 2x^2+x-45
