circuference is equal to the pi*r*2
if r=1ft then...
Circumference is (3.14159)*(1)*(2)
C=6.28318ft
diameter = 1' So radius = 6" So area = pi x 6² = 36 pi = approx 113.097 square inches
You find the sum of the lengths of each side. 36in 1ft 36in 1ft =
1ft 2in = 14in Area = pi*72 = 153.938 square inches to 3 decimal places
1ft = 12in 1ft3 = 1ft x 1ft x 1ft = 12in x 12in x 12in = 1728in3 => 3.25ft3 = 3.25 x 1728in3 = 5616in3
12in = 1ft Therefore 8in + 4in = 12in = 1ft 1ft + 8ft + 2ft = 11ft
how can you write as in circle pie 1ft and 6in
diameter = 1' So radius = 6" So area = pi x 6² = 36 pi = approx 113.097 square inches
You find the sum of the lengths of each side. 36in 1ft 36in 1ft =
8
1ft 2in = 14in Area = pi*72 = 153.938 square inches to 3 decimal places
The surface area is 69.12ft2
To find the area of 3ft by 1ft, you multiply the two. So the area is 3 square feet.
4yd 2ftas 1yd 2ft + 1ft = 2yd6yd 1ft - 2yd = 4yd 1ftthen + 1ft = 4yd 2ft
2 yd - 1ft = 1
Height multiplied by the square of the radius, multiplied by pi (3.142). Make sure all units are the same, don't mix feet and inches - the radius is 0.25 feet, (or the height is 12 inches).
1ft = 12in 1ft3 = 1ft x 1ft x 1ft = 12in x 12in x 12in = 1728in3 => 3.25ft3 = 3.25 x 1728in3 = 5616in3
12in = 1ft Therefore 8in + 4in = 12in = 1ft 1ft + 8ft + 2ft = 11ft
