8 cm Check: 2(5*6) + 2(5*8) + 2(6*8) = 236 cm2 Solved by using algebra.
In the key of C major, 2-5-1 is Dm-G7-C
It is 3 to 5 because 5 dm = 50 cm
For a triangle, the area is equal to half the base times the height. A = 1/2*bh where A is the area of the triangle, b is the length of the base, and h is the height. In this case: * A = 1/2 * 5 * 3 = 15/2 cm2 = 7.5 cm2.
5 dm. 1 dm is 10 cm.
5 ft = 15.24 dm
1 * 11 = 11 cm2 2 * 10 = 20 cm2 3 * 9 = 27 cm2 4 * 8 = 32 cm2 5 * 7 = 35 cm2 6 * 6 = 36 cm2 7 * 5 = 35 cm2 8 * 4 = 32 cm2 9 * 3 = 27 cm2 10 * 2 = 20 cm2 11 * 1 = 11 cm2
2-cm x 3-cm x 5-cmTwo faces are (2 x 3) = 6 cm2 eachTwo faces are (2 x 5) = 10 cm2 eachTwo faces are (3 x 5) = 15 cm2 eachTotal area = 62 cm2
15 dm
The conversion between dm and km are given .On finding the relation we get as follows . 1 km =10000 dm. now, 5 dm=0.0005 km .
1 dm = 10 cm 1/5 dm = 2 cm
The surface area is the total area of all the faces. For a cuboid, all these faces will be rectangular. Example: Find the surface area of a 2 x 4 x 5 cm cuboid. The area of the faces will be: 2 x 4 = 8 cm2 2 x 5 = 10 cm2 4 x 5 =20 cm2 Adding these up give an area of 38 cm2. However we now need to multiply our answer by 2 as there are exactly two of each face. So our final answer is 38 x 2 = 76 cm2.
8 cm Check: 2(5*6) + 2(5*8) + 2(6*8) = 236 cm2 Solved by using algebra.
1 dm = 10 cmSo 5 cm = 0.5 dm
5 dm
The ratio of areas is the square of the ratio of the sides. Ratio of sides is 5:2, so ratio of areas is 52:22 = 25:4 So the larger circle has an area that is 25/4 = 61/4 (= 6.25) times the area of the smaller circle. The difference in areas is given by taking the area of the smaller circle from the area of the larger circle. area_circle = π x radius2 radius = diameter/2 larger_area = π x (5/2)2 cm2 smaller_area = π x (2/2)2 cm2 ⇒ difference = larger_area - smaller_area = (π x 25/4 - π) cm2 = 21π/4 cm2 ≈ 16.49 cm2
5 dm = 50 cm
