Circumference Formula: C = 2πr

r is radius

Area of a Circle Formula: A = πr²

r is radius

Step-by-step explanation:

Step 1: Define

C = 15 m

Step 2: Solve for r

Substitute in variables {Circumference Formula]:                                          15 m = 2(3.14)r[Radius] Multiply:                                                                                               15 m = 6.28r[Radius] [Division Property of Equality] Divide 6.28 on both sides:              2.38854 m = r[Radius] Rewrite:                                                                                               r = 2.38854 m

Step 3: Find Area

Substitute in variables [Area of a Circle Formula]:                                         A = (3.14)(2.38854 m)²[Area] Evaluate exponents:                                                                              A = (3.14)(5.7051 m²)[Area] Multiply:                                                                                                  A = 17.914 m²

Ithink the answer is: it is likely.

That is right sorry i was gonna answer but i already saw his
