C = 43.98 yd to two decimal places
When the radius is known, the formula for circumference is:
C = 2 x pi x r
C = 2 x pi x 7 yd
C = 43.98 yd to two decimal places
circumference = 2 × π × radius
= 2 × π × 7 yards
= 14π yards
≈ 44 yards
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
The radius is 7 inches.
Circumference = 2 pi R = 14 pi = 43.9823 cm (rounded)
circumference=2*pi*r =2*(22/7)*0.25=1.57 inches
14 pi cm or 43.982297150257105338477007365913cmCircumference = 2*pi*7 = 43.98229715 or about 44 cm
The equation for a circle is PiD. The diameter is double the radius, so it is 7 yards in this case. The circumference is 7*PI. Which is approximately 21.98.
6.996451298 or about 7 yards
Radius = 43.96/(2*pi) = 6.996451298 or about 7 yards
Circumference = 2 x PI x radius. So, if circumference = 14 x PI, then the radius is 7
Diameter = 2 x radius = 7 yardsCircumference = Diameter x pi = 7 pi = 21.99 yards (rounded)
If a circle has a circumference of 43.98 the radius is: 7 (6.999).
The radius of the circle is 7.
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
Circumference of a circle = 2*pi*radius or diameter*pi
The circumference is about 43.98 inches. The circumference of a circle is diameter (radius x2) x pi (3.14).
Circumference=πd thefore it is 44
circumference of a circle = 2*pi*radius or diameter*pi
