What is the square ft of a circle with a radius of 70 feet?
Area of the circle: pi*70 squared = 4900*pi square feet
What is the area of a circle with a diameter of 70 mm?
area=pi r squared the r is the radius which is half of the diameter so area =pi mulitplied by 45 squared which is 6361.725124mm
Area of an arch of circle with a radius of 70 feet The angle of the arch is 20 degrees?
855.21 square feet. A circle with a radius 70 would be (pi)(radius squared) = (3.1416) (70) (70) = 15,393.8 square feet. With a 20 degree angle that is 20/360ths of a circle, so multiply your circle area by 20 and divide by 360 = 855.21 square feet.
What is the area of a circle with a radius of 70?
About 15,393.8
What is the area of a circle whose diameter is 70 cm?
Area of a Circle (A) = pi times the radius (r) squared A = (pi) (r)2 Diameter of a Circle (d) = 2 times the radius (r) d = 2r First, find the r Since the diameter (d) = 70 cm, then 70 cm = 2 r (70 cm)/2 = r r = 35 cm Now that you have found the value of the radius (r), you can plug in r for the equation for the area (A) of a circle: A = (pi) (35 cm)2 A = (pi) 1225 cm2 At this point you can multiply 1225 cm2 by pi with a calculator to get the value of 3848.45100065 which can be simplified to 3848.5 cm2
How long is the diameter if the radius is 70 cm?
The diameter of a circle with radius 70 is 140.
What is the area in square feet of a 70 foot circle?
The area of any circle is determined by the formula: A = πr2 where A is the area, π is "pi", the ratio of a circle's circumference to its diameter (approximately 3.1416), and r is the radius of a circle, or half its diameter. If your diameter is 70 feet, the radius is 35 feet. So, ... A = πr2 = (app) 3.1416 x 352 = (app) 3,848 square feet, or about 0.09 acres.
If the circumference of a circle is 70 what would the radius or the diameter be?
70/pi = a diameter of 22.28169203 units
If the circumference of a circle is 70 feet what is the radius?
70/2pi ie 35/pi = 11.14 ft
What is the equation of the circle whose center is 70 and radius is 7?
The equation of a circle with center ((h, k)) and radius (r) is given by ((x - h)^2 + (y - k)^2 = r^2). If the center is 70, we need to specify the coordinates, which could be ((70, 0)) or any other point with 70 as the x-coordinate. Assuming the center is ((70, 0)) and the radius is 7, the equation of the circle would be ((x - 70)^2 + (y - 0)^2 = 7^2) or ((x - 70)^2 + y^2 = 49).
