Make a cylinder, the side area is 9.42 square centimeters, the height is 3 centimeters, its bottom radius is______ Cm, the surface area is______ Square centimeter

Make a cylinder, the side area is 9.42 square centimeters, the height is 3 centimeters, its bottom radius is______ Cm, the surface area is______ Square centimeter

Bottom circumference: 9.42 △ 3 = 3.14 (CM), bottom radius: 3.14 △ 3.14 △ 2 = 0.5 (CM); 3.14 × 0.52 × 2 + 9.42, = 1.57 + 9.42, = 10.99 (cm2); answer: its bottom radius is 0.5 cm, surface area is 10.99 square cm. So the answer is: 0.5; 10.99

Make a cylinder, the side area is 9.42 square centimeters, the height is 3 centimeters, its bottom radius is______ ．

Bottom circumference: 9.42 △ 3 = 3.14 (CM), bottom radius: 3.14 △ 3.14 △ 2 = 0.5 (CM); so the answer is: 0.5 cm

A cylinder has a side area of 9.42 square centimeters and a height of 3cm. What is the radius of its bottom?

Bottom perimeter = side area ／ height = 9.42 ／ 3 = 3.14 cm, bottom radius = 3.14 ／ 2 ／ 3.14 = 0.5 cm ~ I will always answer 523 for you.

The bottom radius of a cylinder is 2 cm, the height is 10 cm, and its side area is () square cm

Side area = 2x3.14x2x10 = 40x3.14 = 125.6 square centimeter, please click [adopt answer], your adoption is the driving force of my answer, if you don't understand,

The side area of the cylinder is 240 square centimeters, the bottom radius is 10 centimeters, what is its volume square centimeters

Height: 240 ^ (3.14 × 10 × 2)
=240÷62.8
=3.82 cm
Volume: 3.14 × 10 × 10 × 3.82
=314×3.82
=1199.48 cm3

There is a cylinder with a volume of 785 cubic centimeters and a bottom radius of 10 centimeters. How many square centimeters is its side area?

According to the meaning of the title, the height is 785 / (3.14 * 10 * 10) = 2.5,
The side area is equal to the perimeter of the bottom multiplied by the height of 3.14 * 2 * 10 * 2.5 = 157

The side area of a cylinder is 8 square centimeters, and its volume is 36 square centimeters. What's its bottom area

If the height of a cylinder increases by 3cm, the surface area will increase by 75.36 square centimeters. How much does the volume of the cylinder increase?

75.36 △ 3 = 25.12 (CM) this is the perimeter. 25.12 △ 3.14 △ 2 = 4 (CM) this is the radius
14 × 4 and 178; × 3 = how many square centimeters

The surface area of a cylinder is 1884 square centimeters, the bottom radius is 10 cm, and the height is calculated? (only the formula is not calculated)

(1884-3.14 × 10 × 2) / (2 × 3.14 × 10) = 20 (CM)

A cylinder is 24 cm high. If its height is reduced by 3 cm, its surface area will be reduced by 18.84 cm. What is the original surface area of the cylinder?

The perimeter of the bottom surface is 18.84 △ 3 = 6.28 cm, the radius is 6.28 △ 3.14 △ 2 = 1 cm, so the original surface area is 1 × 1 × 3.14 × 2 + 6.28 × 24 = 157 square cm
