What happens to the area of a circle if its radius is increased by 20\%?

If radius r of a certain circle is increased by 20\%, then the new radius would be (1.2)r. The area of the new circle would be 1.44 π r2 and the area of the original circle πr2.

What will be the percentage of increase in area of a circle whose circumference is increased by 50\%?

The increase of the area will be 125\%. Given data : The circumference increased by 50\%.

What is the percentage increase in the area of a circle is 44 What will be the percentage increase in its circumference?

So, The Increase Percentage in Circumference of Circles is 20\%.

Is the percentage increase in the area of a circle is 44 What will be the percentage increase in its circumference?

The Circumference of New Circle is 12πx/5. So, The Increase Percentage in Circumference of Circles is 20\%.

When the circumference of a circle decreases from 3p to p by what percent does its area decrease?

1632​ \%

What is the diameter of the circle if the area of the circle is 706.5 cm square?

Diameter of the circle is 30 cm.

What is the length of arc of a sector whose perimeter is 64.8 cm and radius is 12.4 cm?

Length of arc of a sector = 40 CM.

What is the 20\% increase in circumference of a circle?

If the circumference is increased by 20\%, then the diameter must be increased by 20\%, so the radius must be increased by 20\% Circumference is 2πr. 20\% increase in circumference means 20\% increase in radius as 2π is a constant. Early symptoms of spinal muscular atrophy may surprise you.

What happens to the area of a circle when radius increases?

(For example, if the radius increased by 50\% or if the distance between any two particular points increased by 50\% then the area of the whole circle would increase by a factor of 2.25 (which is a 125\% increase), but so would the area of the circle that is outside of an inscribed sq

What is the area of a circle with a circumference of 50\%?

if the circumference of a circle is increased by 50\%, it means its radius is increased by 50\% and it becomes 2(pi)*1.5r = 3(pi)r. Its area will be (pi)(1.5r)^2= 2.25(pi)r^2.

What is the radius of a circle if the area is unity?

If the area of a circle is unity and its radius is increased by 50\%, you can see that the area now will be 2.25 units [1.5^2 = 2.25], which is 125\% increase 125\% is the Answer. It simply follows from the fact that the radius appears as the square in the formula for the area.
