gayaneshka [121]

Answer:

C 5 km

Step-by-step explanation:

so, 5 cm on the map correlates to

5×100000 = 500000 cm in reality.

100 cm = 1 m

1000 m = 1 km

so, 500000 / 100 = 5000 m.

5000 / 1000 = 5 km

Mad math for pi, I have no clue how to do this!!
bogdanovich [222]

To calculate the volume of this figure, we just have to find the volume of the hemisphere and the volume of the cone, then sum them up.

The volume of a hemisphere (the half of a sphere) is given by the formula:

V=\frac{2}{3}\pi r^3

Where r is the radius.

The volume of a cone is given by the formula:

V=\frac{1}{3}\pi r^2h

Where h is the height of the cone.

From the figure we have:

r = 5.3in

h = 9 in

Then, when we substitute these values into the above formulas, we get:

For the hemisphere:

V=\frac{2}{3}\pi r^3=\frac{2}{3}\times3.14\times(5.3)^3=311.6

The volume of the hemisphere is 311.6in^3

For the cone:

V=\frac{1}{3}\pi r^2h=\frac{1}{3}\times3.14\times5.3^2\times9=264.7

As mentioned, the volume of the whole figure is the sum of the volume of the cone and the volume of the hemisphere, then, the volume of the figure is:

V=311.6in^3 + 264.7in^3 = 576.3in^3

Then, the correct answer is option A
