Question

HELP!!!!! how do i get the answer? @jordanloveangel

Answer 1

Match each shape with its surface area. Use three point one four for pi and round to the nearest whole number where necessary.

Match Term Definition
square pyramid: base length ten meters, slant height 5 meters A) two hundred square meters
cone: radius 8 meters, slant height 6 meters B) three hundred fifty-two square meters
square pyramid: base length eleven meters, slant height 6 meters C) two hundred twenty square meters
cone: radius 5 meters, slant height 9 meters D) two hundred fifty-three square meters

Answer 2

hold one let me see ~.^

Answer 3

OK ;)

Answer 4

two hundred twenty square meters

Answer 5

surface area of square pyramid = (length base)*(length base) + 4*(1/2)*(length base)*(slant height)
surface area of cone: π · r^2 + π · r · squareroot(r^2 + h^2)
pi*(radius)*(radius) + pi*(radius)* (square root ((radius)*(radius) + (height)*(height))))


sorry I was thinking actual height... you were given slant height
so that would be
pi*(radius)*(slant height) + pi*(radius)*(radius)
