The 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
94.985 or approximately 95 square centimeter.
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.
8011.846665 or 8012 square feet to the nearest square foot
The radius, to the nearest hundreth, of a circle whose area is 719 square feet is 15.13.Another Answer:-When: pi*radius2 = 719 square feetThen: radius = square root of 719/pi => 15.13 feet rounded to the nearest 1/100
380.13 square cm.
94.985 or approximately 95 square centimeter.
42 cm
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
90 square inches
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.
8011.846665 or 8012 square feet to the nearest square foot
The area of a circle with a circumference of 13 is: 13.45 square units.
The area of a circle with a diameter of twelve inches rounded to the nearest whole number is 113 square inches.
