Answer:
<em><u>468.8 feet²</u></em>
Step-by-step explanation:
2×(5.2×10 + 5.2×12 + 10×12) = <em><u>468.8 feet²</u></em>
6+ 9.43 = 15.43
3 is the radius so the diameter is 6.
d • pi is the equation for circumference.
6 • pi is approximately 18.85
and because its a semi circle, you divide that by half and get 9.43
then add the diameter and half the circumference which = about 15.43 and thats the perimeter.
