Step-by-step explanation:
Answer:
3.14 yards^2
Explanation:
The formula for the area of a circle is pi times the radius^2.
You have to substitute a yard into the radius.
The base length will be found as follows:
volume of the triangular prism is given by:
V=1/2ab×h
where:
10 ft
b=6.9 ft
thus the height will be found as follows:
276=1/2×10×6.9×h
solving for h we get:
h=276/34.5
h=8 ft
