# What happens to the areas when its radius is tripled? ### What happens to the areas when its radius is tripled?

Complete step-by-step answer: The area of a figure is the number of unit square space that it covers, generally expressed in square centimeter or square meter. Therefore we can say that the area becomes 9 times when the radius of the circle is tripled.

### How does the lateral surface area change when the radius is tripled?

From (i) and(ii) we can see that there is no change in LSA even if the radius is reduced to one-third and height is tripled. The Lateral surface area remains the same. Hence [option 3: it remains the same] is the correct answer.

### When the radius of a circle triples does its circumference triple?

1 Expert Answer If you triple the radius, the circumference also triples because r and C are directly proportional.

### What happened to the surface area of the height is tripled?

Explanation: . Doubling the dimensions makes the surface area 4 times the original surface area. Tripling the dimensions makes the surface area 9 times the original surface area.

### What happens to the lateral area of cylinder when the radius is doubled?

If the radius of a cylinder is doubled, its lateral surface area is doubled. If we want to keep the lateral surface area constant, it is necessary that should be constant. The height should be halved.

### What is the radius of a cylinder with a diameter of 18 cm?

Answer: 9cm. Step-by-step explanation: A diameter is twice the length of a radius.

### How many times larger is the volume of a cylinder if the radius is multiplied by 7?

1 Expert Answer In the equation, substitute 3r for r and you will see that the volume is 9 times larger.

### How many times larger is the volume of a cylinder if the radius is quadrupled?

4 Answers By Expert Tutors V = (pi)r2h is the formula for the volume of a cylinder. The formula becomes V = (pi)(2r)2h if the radius is doubled and the height remains the same. V = 4(pi)r2h after simplifying. The volume increases 4 times since the resulting equation is 4 times the original equation.

### What happens when the radius of a cylinder is tripled?

When calculating volume, one of them is a square and the other is linear so the answer here could be the volume changes by a factor of 3 (the height is tripled) a factor of 9 (the radius is tripled) or a factor of 27 (3*9 when both are tripled). Just focus on the formula and suppose any value of height and cylinder and triple it.

### How many times will the surface area of a cylinder increase?

If radius of cylinder is tripled and height remains same (i) how many times will its surface area increase? (ii) how many times will its volume increase? 1.The surface area will become 4 times ie increase by 3 times if both radius and height of the cylinder are doubled.

### What happens to the volume of a sphere when it is tripled?

sikringbp and 1 more users found this answer helpful. The volume of a sphere is proportional to the cube of its radius: If the radius is tripled so that the new radius is , then the new volume would be. In other words, an increase in the radius by a factor of 3 results in an increase in volume by a factor of . 0.0.

### How does the volume of a cylinder change?

If the length of a cylinder were to double, then the volume of the cylinder will double. Volume for a cylinder is defined by length times diameter. How does the volume of a cylinder change if the radius is tripled?
