Answer:
23) 35.77 in²
25) 48.19 cm²
Step-by-step explanation:
Use the appropriate area formula with the given information.
__
23) The area of a triangle is given by the formula ...
A = 1/2bh . . . . . base b, height h
A = 1/2(9.8 in)(7.3 in) = 35.77 in²
__
25) The area of a parallelogram is given by the formula ...
A = bh . . . . . . base b, height h
A = (7.9 cm)(6.1 cm) = 48.19 cm²
_____
The <em>height</em> in each figure is <em>measured perpendicular to the base</em>. This tells you that the length 10.6 cm of the diagonal side of the triangle is not relevant to finding the area.

Answer:
226.4 m³.
Step-by-step explanation:
The volume of a right cone with a circular base is:
,
where
is the volume of the cone,
is the radius of the cone,- and
is the height of the cone.
The radius of the circular base is one-half its diameter.
.
.
C=2pr
r=C/(2p) and we are given C=85 so
r=85/(2p) meters
r≈13.53 meters (to nearest one-hundredth of a meter)
