Designed for students, the document includes twelve distinct problems requiring the application of geometric formulas. Each problem requires students to compute the area and round the final result to one decimal place. The document also incorporates an answer key for all twelve problems, enabling self-assessment and verification of the calculations performed. It is an ideal tool for reinforcing geometry concepts and proficiency in mathematical problem-solving through repeated practice and immediate feedback. The clear layout and step-by-step format make it highly effective for classroom assignments or independent study sessions targeting fundamental area calculations.",{"@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/area-of-a-semi-circle-2b-practice-worksheet/633397/",{"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/area-of-a-semi-circle-2b-practice-worksheet/633397.png","ImageObject",300,407,{"name":92,"@type":93},"Margaret","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-25","2026-10-22",true,{"@type":102,"interactionType":103,"userInteractionCount":14},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"How is the area of a semi-circle calculated in this worksheet?","Question",{"text":112,"@type":113},"The area is calculated using the diameter of the semi-circle, applying the standard geometric area formula for a circle halved, with results rounded to one decimal place.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What units are used in the exercises?",{"text":117,"@type":113},"The problems utilize various units of measurement including centimeters (cm), meters (m), and millimeters (mm).",{"name":119,"@type":110,"acceptedAnswer":120},"Does the document provide solutions to the problems?",{"text":121,"@type":113},"Yes, the second part of the document contains an answer key that provides the calculated area for each of the twelve problems.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},633397,1792942059,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":19,"category_name":20,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":14,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":14,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":143,"read_time":24},137451207643,"https://ap-avatar.wpscdn.com/davatar_3d24733baf745e90a7e4bdd5f77d97b2","Name Date  \nAREA OF A SEMI-CIRCLE 2B  \nWork out the area of these semicircles using the diameter measurements.
