The side view of a cylinder is just a square with a side length of 18.84 cm. Its bottom radius is () cm, and its height is () cm?
Bottom perimeter = height = 18.84
2*3.14*r=18.84
r=3
therefore
The side view of a cylinder is just a square with side length of 18.84 cm. Its bottom radius is (3) cm and its height is (18.84) cm
Expand the side of a cylinder to get a square. The side length of the square is 18.84 cm. How many cm is the radius of the bottom of the cylinder and what is the side area
Radius = 18.84 ／ 2 ／ 3.14 = 3cm
Side area = 18.84x18.84 = 354.9456 square centimeter
A can of beer, its packaging side view is just a square with side length of 18.84 cm. The bottom radius of this can of beer is______ Gao Shi______ ．
According to the analysis, the height of the cylinder is 18.84cm, and the bottom radius of the cylinder is 18.84 △ 3.14 △ 2 = 6 △ 2 = 3 (CM); answer: the bottom radius of the cylinder is 3cm, so the answer is 3cm, 18.84cm
If the side expansion of the cylinder is a square with a side length of 3.14 decimeters, what is the height of the cylinder______ And the bottom area is______ ．
The side expansion of the cylinder is a square with side length of 3.14 decimeters, that is, the perimeter and height of the bottom surface are 3.14 decimeters, the bottom area: 3.14 × (3.14 △ 3.14 △ 2) 2, = 3.14 × 0.52, = 3.14 × 0.25, = 0.785 (square decimeter); answer: the height of the cylinder is 3.14 decimeters, the bottom area is 0.785 square decimeter
