A container in the shape of a pyramid has a rectangular base with dimensions of 5 inches by 15 inches. The height of the rectangular pyramid is 12 inches. Marbles fill half the volume of the container. How many more cubic inches of marbles are needed to finish filling the container?Enter your answer in the box. { }in3

First you find the volume of the pyramid:

1. find the area of the base:

A= 15 x 5= 75

2. Multiply the Area of the rectangle by the height; h= 12 and si use the result by 3.

V= A x h /3 =. 75 x 12 = 900 /3

V= 300

3. If only 1/2 is filled, that means

V= 300/2= 150 in3 is filled and

150 in3 of marbles is needed to fill the container.

150

Step-by-step explanation:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
