∙ 15y agoThe area of a circle is equal to 2(pi)r, where pi = 3.141. So,
154 = (2)(3.141)(r)
r = 154/6.282
r = 24.5 Since after decimal point you have 5, round 24.5 to 25.
The radius is 25cm

The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
You cannot change square centimeter to centimeter. The square centimeter is a measure of area and the centimeter is a measure of distance.

The area of a circle to the nearest tenth if its radius is 4.5 is: 63.6 square units.
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
Area of a circle with radius 3.2: pi*3.2 squared = 32.17 square units rounded to 2 decimal places

You cannot change square centimeter to centimeter. The square centimeter is a measure of area and the centimeter is a measure of distance.
Suppose you had a rectangle that was 12.75 units by 19.6 units. The area would be 249.9 square units which would round to 250 square units to the nearest square unit. Since a centimeter isn't a square unit, it can't be rounded to the nearest square unit.

The area of a circle with a circumference of 13 is: 13.45 square units.
Beautiful problem !The circle has more area.If you have a circle and a square, with the circumference of the circle equal tothe perimeter of the square, then the area of the circle is always(4/pi) = 1.27324times as much as the area of the square.If you have some length of fence in your warehouse, the most land you canenclose with it is to set it up in a circle.
