What is the volume of this right cone? 27π cm³ 200π cm³ 213π cm³ 300π cm³ note: image is not drawn to scale. A cone with a radius of 10 centimeters, a height of 9 centimeters, and a slant height of 13. 5 centimeters.

In the image, layer a is the topmost layer. layer c contains fossils from the precambrian era. layer b contains dinosaur fossils, and layer a contains fossils of mammals. which two statements are supported by this evidence? 1. mammals lived before the precambrian era. 2. dinosaurs and mammals existed in the precambrian era. 3. dinosaurs evolved after precambrian organisms. 4. precambrian organisms evolved after dinosaurs. 5. precambrian organisms were the first life-forms to become fossilized, according to this sample.

Scientists observed a rock stratum with fossil. if mollusks evolved before arthropod, where will their fossils be found.

Find the number if 3.7% of it is 37% of 37.
