Surchallenge Area Meaning

(S A=2 B+P h) | Find the area of each confront. Add up all locations. | |

(S A=B+dfrac12 s P) | Find the location of each challenge. Add up all areas. | |

(S A=2 B+2 pi r h) | Find the area of the base, times 2, then add the locations to the areas of the rectangle, which is the circumference times the height. | |

(S A=4 pi r^2) | Find the location of the excellent circle and also multiply it by 4. | |
