I need help on number 18
zloy xaker [14]

Answer:

Volume = 35185.8 km^{3}

Step-by-step explanation:

Recall the formula for the volume of a cone: Volume = \pi  R^{2}  \frac{h}{3}

Where R is the radius of the cone's circular base (in your case half of 80 km,(that is 40 km)

And h stands for the height of the cone (in your case 21 km)

We replace such in the formula and calculate its final value:

Volume = \pi 40^{2} \frac{21}{3} = \pi  1600 \frac{21}{3} = \pi 1600 (7) = 35185.83772...

We round it to the number of decimals your problem request (let's say to one decimal) and also include the cubic units:

Volume = 35185.8 km^{3}
