301.44 cm2
100.48 cm2
150.72 cm2

Answer 1

@g17

Answer 2

just put the value in formula

Answer 3

for
l =sqrt(h^2+r^2)=sqrt(64+36)=sqrt 100=10

Answer 4

l=10
and r=6

Answer 5

sorry idk what your talking about sadly

Answer 6

there is a right angle triangle
so use pythagorse theorm to find l

Answer 7

im not that smart

Answer 8

PYTHAGORSE THEORM
hypotenuse ^2=base^2+perpendicular^2

Answer 9

here h is perpendicular
and r = base
