A = pi * r^2
R = D / 2
R = 7 / 2
R = 3.5
A = 3.14 * 3.5^2
A = 3.14 * 12.25
A = 38.465
Divide it by 2 since its a semi-circle:
38.465 / 2 = 19.2325
So about 19 square feet.

Step-by-step explanation:
Answer:
height ≈ 11.9 units
Step-by-step explanation:
Construct a perpendicular bisector from the vertex to the base, thus splitting the triangle into 2 right triangles.
Using the sine ratio in one of these right triangles, then
sin48° =
( the opposite is the height h )
sin48° =
( multiply both sides by 16 )
16 × sin48° = h , thus
h ≈ 11.9 ( to the nearest tenth )
