What is the circumference of a circle if r equals 21?
Remember the circle eq'n ;- C = 2 pi r Hence When r = 21 C = 2* 3.14 * 21 = C = 131.88 units.
How many square feet is in 21 yards?
A square foot is a unit of area. A yard is a unit of length. The two units are therefore incompatible.
Parallelogram PAKE has diagonals PK and AE intersect at R perimeter of triangle AKE equals 33 perimeter PAKE equals 42 length of AE is?
Perimeter of PAKE = 42 units so PA + AK + KE + EP = 42 units But, since PAKE is a parallelogram, PA = KE and EP = AK which gives KE + AK + KE + AK = 42 units or AK + KE = 42/2 = 21 units. Now, perimeter of AKE = 33 units that is AK + KE + EA = 33 units But AK + KE = 21 units so 21 + EA = 33 units so EA = 33 - 21 = 12 units.
What is the ratio of 63 33 and?
The ratio of 63 to 33 can be calculated by dividing 63 by 33, which equals approximately 1.91. This means that for every 33 units, there are approximately 63 units, resulting in a ratio of 63:33 or simplified to 21:11.
