The area, A, of a circle is given by the formula A r , r where r is the radius of the circle. It’s given that the area of the circle is b square 2.1 inches, where b is a constant, and the radius of the circle is inches. r 2.1 =r 2 r=r 2.12 Substituting b for A and for r in the formula A r yields b ^ h. r =4.41 Dividing both sides of this equation by yields b . Therefore, the value of b 4.41 is .</p>","correct_answer":["2"],"has_media":false,"has_mathml":false,"has_table":false,"source_created_at":null,"source_updated_at":null,"options":[],"attribution":{"source_id":"cb_practice_pdf","source_name":"College Board full-length SAT practice tests (PDF)","rights_holder":"College Board","canonical_url":"https://satsuite.collegeboard.org/practice/practice-tests/paper","retrieved_from":"https://satsuite.collegeboard.org/practice/practice-tests/paper","attribution":"Full-length SAT practice tests 4–11 © College Board, published free at satsuite.collegeboard.org.","disclaimer":"Extracted from PDF layout: equations, figures and tables do not survive intact.
