Answer:
C. 28 ft³
Step-by-step explanation:
The general formula for the volume of a pyramid:
V =
, where B = the area of the base and h = height of the pyramid
Since the base is a rectangle, we can find area using the formula:
A = l x w or A = 3 x 4 = 12 ft²
Using B = 12 and h = 7:
V = ![\frac{(12)(7)}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B%2812%29%287%29%7D%7B3%7D)
V = 28 ft³
The top surface area of the wedge with central angle of π / 2 radian is 9π / 4 inches square
<h3>How to find area of a sector?</h3>
The area of the top surface of the the wedge is the area of a sector.
Therefore,
area of the top surface = ∅r² / 2
area of the top surface = π / 2 × 3² × 1 / 2
area of the top surface = π / 2 × 9 × 1 / 2
area of the top surface = 9π / 4
area of the top surface = 9π / 4
area of the top surface = 9π / 4 inches squared

The numbers would be 1 and 6 you need to put the positive on the 6 and the negative on the 1 to get positive 5 when adding and -6 when multiplying
Hope this helps
First convert the total km's to miles:
4.8 km / 1.609 km per mile = 2.983 miles.
Now convert miles to feet:
2.983 miles x 5280 feet per mile = 15,751.39 feet Rounds to 15,751.40 feet
