Answer:

4 $m^{2}$ $k^{2}$ ;28 $k^{2}$ ;8 km

9m $m^{2}$ k;63mk; 18 $m^{2}$

Step-by-step explanation:

4k· $m^{2}$ k=4 $m^{2}$ $k^{2}$

4k·7k=28 $k^{2}$

4k·2m=8km

9m· $m^{2}$ k=9m $m^{2}$ k

9m·7k=63mk

9m·2m=18 $m^{2}$

Se multiplican los números y luego las letras

Si se multiplican dos letras iguales lo elevamos al cuadrado

EJEMPLO:m· m= $m^{2}$

Find the volume of the composite solid. Round your answer to the nearest tenth

Llana [10]

Answer:

1131.0 m^3

Step-by-step explanation:

Let h1 represent the height of the top cone, and h2 the height of the bottom cone. The volume of a cone is given by the formula ...

V = (1/3)πr^2·h

so the volumes of both cones together will be ...

V = (1/3)πr^2·h1 + (1/3)πr^2·h2 = (1/3)πr^2·(h1 +h2)

= (1/3)π(6 m)^2(12 m + 18 m) = 360π m^3

≈ 1131.0 m^3
