- Divide 40 by Pi (3.14159265);
- and then obtain the square root of the resulting number;
- and then multiply that number by 69.57 to get the answer in yards.
The answer is: approximately 248.24 yards.

What is the surface area of a cone with a slant height of 40 and a radius of 20?
A slant height of 20 and base circle radius (r) of 20 gives slant length (s) = 28.284 equation for cone surface area : (pi * r * s) + (pi * r2) = 1777.136 + 1256.637 = 3033.773 units2

What would the perimeter of a 20ft semicircle be?
That depends on what you mean by a "20 ft semicircle".A semi-circle is a half circle.A 20 ft circle could be:A circle of diameter 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2π 20 ft + 20 ft= 10π + 20 ft≈ 51.42 ftA circle of radius 20 ftThe perimeter of the semicircle is half the circumference plus double the radius → perimeter = 1/2 2π 20 ft + 2 x 20 ft= 20π + 40 ft≈ 102.08 ftA circle of circumference 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2 20 ft + 20 ft ÷ π= 10 ft + 20/π ft≈ 16.37 ftHowever, if a 20 ft circle is a circle with a circumference (= perimeter) of 20 ft then a 20 ft semi-circle could be a semicircle with a perimeter of 20 ft→ perimeter = 20 ft
What is the radius of a circle of perimeter 40 cm?
Radius = 40/2pi cm
What is the radius of a circle with a circumference of 40 inches?
radius = 40/(2*pi) in inches
What is the area of a circle with a radius of 40cm?
A circle with a radius of 40 cm has an area of 5,026.55 square cm.
Is a circle with a area of 40 more less or same than a circle with a radius of 4?
In order to even discuss this question, we must assume that the unit of the '40' is the square of the unit of the '4'. -- The radius, diameter, and circumference of the circle with an area of 40 are each 10.794% shorter than the corresponding measurement in the circle with radius = 4 . -- Its area (40) is 20.423% less than the area of the circle with the radius of 4 .
What is the radius of a circle whose circumference is 40 pi?
