Calculate the total surface area of a solid cone of slant height 15cm and base radius 8cm.

1155.52

Explanation:

because the formula is 2πrh+2πrsquared

so 2(3.14)(8)(15)+2(200.96)= 1155.52

and you get 200.96 by doing your circle formula for area , which is A=πrsquared

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the answer is 12 as i may remember
