Vtotal = Vcone 1+Vcone 2 Find the volume of the composite solid.
Use 3.14 for pi.

The correct answer is: 891.76 cm³

We have given the dimensions of a Cones in the given figure
For Cone 1
Radius, r = 6 cm
Height, h = 7 cm
For Cone 2
Radius, R = 10 cm
Height, H = 6 cm
We have to find the volume of the given cone
We know that
Volume of a Cone 1 = ()πr²h

= ()(3.14)(6 x 6)(7)

= ()(3.14) (36 x 7)

= ()(3.14)(252)

= 791.28 / 3

= 263.76 cm³

Volume of a Cone 1 = ()πR²H

= ()(3.14)(10 x 10)(6)

= ()(3.14) (100 x 6)

= ()(3.14)(600)

= 188

= 628 cm³
We know that V_total=V_{cone 1}+V_{cone 2}
V_total = 263.76 + 628 = 891.76 cm³
Therefore, the total volume of the composite solid is 891.76 cm³
Therefore correct option is a)891.76 cm³ .
