Answer:
55.4 in³
Step-by-step explanation:
The formula for the volume of a pyramid can be found:
V = , where B = area of the base and h = height of the pyramid
Since the base is a triangle, we need to use the formula for the area of a triangle:
A = =
Next, multiply the area of the base by the height of the pyramid:
17.67 x 9.4 = 166.098 ÷ 3 ≈ 55.4 in³

Answer:
3 times more.
Step-by-step explanation:
The odds of landing a dart in any of the circles correspond to the surface area of the circle.
Calculate the surface area of both circles:
The formula for the area of a circle is .
- inner circle:
- for the outer circle, use the formula then subtract the value of the inner circle, to find the remaining area:
Calculating greater chance:
Divide the larger area by the smaller area:
That means that the area of the outer circle is 3 times larger, making it 3 times more likely to hit the outer circle. Therefore the points for hitting the inner circle should be 3 times more.
