If the circumference of a circular sheet is 176m , find its area |
| Answer» CIRCULAR sheet withCircumference = 176 mWhat To FIND:Area of the circular sheet.How To Find:To find the area of the circular sheet, we will FIRST find the radius of the circular sheet.Formula Used:Circumference = 2πrArea = πr²Solution:FINDING the radiusUsing the formula,⇒ Circumference = 2πrSubstitute the value,⇒ Multiply 2, 22 and r,⇒ Take 7 to LHS,⇒ Multiply 176 by 7,⇒ 1232 = 44rTake 44 to LHS,⇒ Divide 1232 by 44,⇒ 28 m = rFinding the areaUsing the formula,⇒ Area = πr²Substitute the value,⇒Cancel 7 and 28,⇒ Area = 22 × 4 × 28Mutiply the numbers,⇒ Area = 2464 m²∴ Thus, the area of circular sheet is 2464 m². | |
