Anyone know the answer?

C : the total volume is 117

Step-by-step explanation:

we need to find the volume of each object and then add them together at the end

ill call the smaller object #1 and the bigger object #2

#1:

volume = length * width * height

v = Lwh

v = 4 * 3 * 1 = 12

the volume of the first object is 12 (remember the unit of volume is always cubed)

#2:

v = Lwh

v = 7 * 5 * 3 = 105

the volume of the second object is 105

now let's add them together to find the combined volume!

object 1 + object 2 = total combined volume

12 + 105 = 117

the total volume is 117 (or option C)

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'.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
