The radius will be about 5.87 (units).

The formula for the area is A = (pi) r2

where pi is about 3.1416 and r is the radius (squared)

108 = 3.1416 (r2)

34.38 = r2

r = about 5.87

A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. 648 feet of fencing is used. Find the dimensions of the playground?

Without further information it is impossible to say what the dimensions are; only an equation can be given relating the width to length which will have infinitely many solutions as there are 2 unknowns: Let one dimension of the playground be x and the other be y; let the extra fence be constructed parallel to the side of length x. Then: total fence used = perimeter of rectangle + fence across the middle → 648 ft = 2x + 2y + x → 2y + 3x = 648 ft As we only have 1 equation but 2 unknowns, there are infinitely many possible solutions, eg: 2 ft wide by 321 ft long, split with a fence parallel to the 2 ft side; 4 ft wide by 318 ft long, split with a fence parallel to the 4 ft side; 129 ft wide by 130 ft long, split with a fence parallel to the 130 ft side. If the problem included other information, for example: the area of the playground is a maximum, then: From above: 2y + 3x = 648 → y = 324 - 3x/2 and area = xy → area = x(324 - 3x/2) → area = 324x - 3x²/2 To find the maximum area, completing the square gives: area = 3/2 (216x - x²) → area = -3/2 (x² - 216x) → area = -3/2 ((x - 108)² - 108²) → area = 3/2 (108² - (x - 108)²) As x varies (x - 108)² is greater than or equal to 0, and the greater it is the smaller the area is; the maximum area is when (x - 108)² is a minimum, ie: (x - 108)² = 0 → x - 108 = 0 → x = 108 → y = 324 - 3 × 108 / 2 = 162 Thus the maximum area is when the playground is 162 ft long by 108 ft wide with the dividing fence parallel to the 108 ft side.


If one side of an equilateral triangle is 12Cm find the Area?

Use Pythagoras' theorem to find the triangle's altitude or height: 122-62 = 108 and the square root of this is 10.39230485 1/2*base*height = area 1/2*6*10.39230485 = 31.17691455 square units


What is the area of a rectangle with a diagonal of 15 and a length of 9?

Diagonal = 15 and Length = 9 units.Therefore, by Pythagoras, Breadth = sqrt(152 - 92) = sqrt(144) = 12 units.So area = 9*12 = 108 sq units.Diagonal = 15 and Length = 9 units.Therefore, by Pythagoras, Breadth = sqrt(152 - 92) = sqrt(144) = 12 units.So area = 9*12 = 108 sq units.Diagonal = 15 and Length = 9 units.Therefore, by Pythagoras, Breadth = sqrt(152 - 92) = sqrt(144) = 12 units.So area = 9*12 = 108 sq units.Diagonal = 15 and Length = 9 units.Therefore, by Pythagoras, Breadth = sqrt(152 - 92) = sqrt(144) = 12 units.So area = 9*12 = 108 sq units.

What is the radius of a circle if the area is 108cm?

You know that the formula of area for a circle is = pi * r^2 ... r being the radius. Therefore, you can plug it in to solve. pi * r^2 = 108. You need to isolate r, so you would divide by pi for both sides. r^2 = 34.378 . Then you can square root both sides r = 5.68 . Of course, I am rounding! So you if you want an exact answer, leave the pi sign!


What is the area of a parallelogram with a circle inside the base of the parallelogram is 9 and the diameter of the circle is 6?

Since the area of the circle would be multiplied due to the circumference of the pathogenic therum,so you would multiply 54x2=108.Then multiply that by 54,which is the absolute value of the area of the parallelogram,so 54x108,is 5832,which you'd find the square root of,76.4. :)


What is the diameter of a 54 inch circle?

It depends on what you mean by a certain size circle. If the certain size is the diameter, then the answer is 54 inches. If the certain size is the radius, then the answer is 108 inches. If the certain size is the circumference, then the answer is 54 / 3.14159 or about 17.19 inches

If a spherical bubble has a volume of 36 pi cm cubed calculate the surface area of the bubble?

you need to work backward for find the radius from the volume then work forward and find the surface area. The volume is 36 Pi cm3 The formula for the volume inside of a sphere is 4/3 Pi x radius3 so 36xPi=4/3 Pi x radius3 So 108/4=the radius3 so 27 is the radius cubed hence 3 is the radius. This tells us the surface area is 4xPix32 =36Pi cm squared. So in the surface area is also 36 but the units are square cm.
