Answer:
the one for the finding the height is 3.3, the one with 7 as the height is 351.86, and the one with 3 as the height is 150.8
Step-by-step explanation:
h=V
πr2=41.5
π·22≈3.30247
V=πr2h=π·42·7≈351.85838
V=πr2h=π·42·3≈150.79645
Answer:
(a is size of side of triangle)
the perimeter of equilateral triangle =3a
or, 36=3a

=√3/4*(13^2)
=73cm^2
