This statement is true.

A pyramidal number tells the number of balls that could be stacked evenly with square bases. If were are looking for the nth pyramidal number, that is a pyramid with a square base that is n by n.

Answer:

\text{1. }50^{\circ}\\\text{2. }80^{\circ}

Step-by-step explanation:

1. The measure of an inscribed angle is always half the measure of the arc it forms. Since angle ACB forms arc AB with a measure of 100 degrees, the measure of angle ACB will be equal to \frac{100}{2}=\boxed{50^{\circ}}.

2. Relating to problem 1, both inscribed angles marked in the figure form the same arc. All inscribed angles forming the same arc will have the same measure. Therefore, the measure of angle GEF is equal to \boxed{80^{\circ}}.

Which expression represents the volume, in cubic units, of the composite figure? One-third(8)(6)(6) (8)(6)(4) One-third(8)(6)(10
vaieri [72.5K]

The expression of Volume in cubic meter  \frac{1}{3} (8)(6)(6)+(8)(6)(4)

The correct option is (1)

<h3>What is Volume?</h3>

Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.

Volume will be,

V= Volume of rectangular pyramid + Volume of cuboid

 

Volume of rectangular pyramid= \frac{1}{3} * base area* height

                                                   = \frac{1}{3} * 6*8*(10-4)

                                                   =\frac{1}{3} * 6*8*6

Volume of cuboid= l*b*h

                              = 4*6*8

So, Volume   =\frac{1}{3} * 6*8*6 + 4*6*8

                     = \frac{1}{3} (8)(6)(6)+(8)(6)(4)

So, The expression of Volume in cubic meter  \frac{1}{3} (8)(6)(6)+(8)(6)(4).
