It includes three distinct exercises involving real-world objects such as a pond, a mirror, and a patio, with varying units of measurement including meters and centimeters. Each problem requires the application of geometric principles, specifically involving the radius and diameter to determine total boundary length. A corresponding answer key is included to provide step-by-step working and solutions for each problem, helping students verify their calculations and understand the methodology for deriving the curved part and the diameter sum.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/perimeter-of-a-semi-circle-problems-1b/637507/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/perimeter-of-a-semi-circle-problems-1b/637507.png","ImageObject",300,407,{"name":92,"@type":93},"awa","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-22",true,{"@type":102,"interactionType":103,"userInteractionCount":19},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"How is the perimeter of a semi-circle calculated?","Question",{"text":112,"@type":113},"The perimeter of a semi-circle is calculated by adding the length of the curved part (which is half the circumference of a full circle) to the diameter of the semi-circle.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What is the perimeter of a semi-circular pond with a 3-meter diameter?",{"text":117,"@type":113},"The perimeter is calculated as (1.5 * π) + 3, resulting in approximately 7.7 meters when rounded to one decimal place.",{"name":119,"@type":110,"acceptedAnswer":120},"How do you determine the perimeter of a semi-circular mirror with a 25 cm radius?",{"text":121,"@type":113},"First, calculate the diameter (2 * 25 cm = 50 cm).
