How to calculate the sum of 1 / 65 + 3 / 52 and * 13 + 4 / 5

(1 / 65 + 3 / 52) x13 + 4 / 5 = 1 / 65x13 + 3 / 52x13 + 4 / 5 = 1 / 5 + 4 / 5 + 3 / 4 = 1 + 3 / 4 = 1 and 3 / 4

1 and 5 / 4 * (1 and 3 / 2 + 2.5) - 0.65/2 and 6 / 1

1:5 4 * (1:3 2 + 2.5) - 0.65/2:6 1
=9/5x5/3+9/5x5/2-13/20÷13/6
=3+4.5-0.3
=7.2

There is some water in the cuboid glass container. The bottom surface of the inner wall of the container is 14cm long and 9cm wide. Now put two equal bottom and height cylinders and cones. The water surface rises by 2cm and the cone is completely immersed in water. One sixth of the volume of the cylinder is exposed outside. The volume of the cylinder and the cone can be solved by equations

14 × 9 × 2 = 252 CC
3×（1-1/6）=2.5
Cone volume: 252 ÷ (1 + 2.5) = 72 cm3
Cylinder volume: 72 × 3 = 216 cm3

Use a piece of iron wire to form a square, the perimeter is 25.12 cm, use the same length of iron wire to form a circle, how many square centimeters is the area of the circle? Question 2: use two 12.56 meters long ropes to circle a circle and a square respectively, which figure has the largest area and how much?
Can you play better... I don't understand

(1) 25.12 divided by 3.14 equals 8 (CM) 8 divided by 2 equals 4 (CM) 3.14 times (4 times 4) equals 50.24 (square cm) (2) 12.56 divided by 3.14 equals 4 (meters) 4 divided by 2 equals 2 (meters) 3.14 times (2 times 2) equals 12.56 (square meters) 12.56 divided by 4 equals 3.14 (meters) 3.14 times 3.14 equals 9.8596 (square meters

An object moving along the east-west direction with uniform velocity is 3.0 m / s when it passes through point a at a certain time, and the direction is eastward. After 2 s, it passes through point B, which is 10.0 m to the west of point a. the acceleration of the object and the velocity when it passes through point B are calculated

According to the law of uniform variable speed linear motion, there are: x = V0 + & nbsp; v2t speed is 3.0 m / s when passing through point a at a certain time, and the direction is eastward, after 2 s, it passes through point B, and point B is 10.0 m to the west of point a, which is the positive direction, - 10 = 3 + & nbsp; V2 × 2V = - 13m / s, the negative sign indicates that the velocity direction at point B is opposite to the positive direction, that is, to the West. According to the definition of acceleration a = △ V △ T, a = − 13 − 32 = - 8m / S2, the negative sign indicates that the acceleration direction is opposite to the positive direction, that is, to the West. A: the acceleration of the object is 8m / S2, that is, to the West. When passing through point B, the velocity is 13m / s, that is to the West
