Sorry but i only know the answer for the 1st question.
--------------------------
If the angles are complementary they measure 90°.
1st find half of 90
which is 45.
Find 4 more than 45.
which is 49°
then subtract 90-49=41
so the measurement of the 2 angles are
49 and 41
Hope it helps!!
Answer:
12,600
Step-by-step explanation:
So in order to compare, the measurements have to same units. So lets convert everything to feet.
George 2 yds = 6 ft Kelsey 68 inches = 5 ft 8"
Mariah 5 feet Brian 5 ft 10 "
George measured the tallest at 6'
Hope this helped.
Step-by-step explanation:
volume of the cyclinder=πr²h
=π×6²×12
=432π cm³
volume of a cone=1/3πr²h
=1/3π×9×8
=24π cm³
number of cones=432π/24π=18 cones
