Answer 1

Answer: The equation to find the volume of a pyramid is V= $(lwh)/(3)$
3.) V= $(3*4 (2)/(3) *3 (1)/(3) )/(3)$ → Multiply the top V= $(46 (2)/(3) )/(3)$ → Divide by 3 V= $15 (5)/(9)$
4.) V= $(2.6*6.4*10.8)/(3)$ → Multiply the top V= $(179.712)/(3)$ → Divide by 3 V=59.904 or V=59.9
5.) Since you need to find h you put the V value in and keep the h value blank. 1,350= $(15*15*h)/(3)$ → 1,350= $(225*h)/(3)$ → Multiply 3 by both sides 3×1,350= $(225*h)/(3)$ ×3 → 4,050=225×h → Divide 225 from both sides 4,050÷225=225×h÷225 → 18=h

I hope that helps!

A rectangle with an area of 100 square inches and a perimeter of 40 feet must have sides of 10 feet each, making it a square. A rectangle with the same area and any other perimeter would therefore not be a square.

The sum of the measure of the interior angles of a polygon is 2160°. What polygon is it? 14-gon 12-gon 13-gon 15-gon

Answers

Answer:

It is a 14-gon.

Step-by-step explanation:

Sum of internal angles of an n sided polygon = 180(n - 2) degrees.

2160 = 180(n - 2)

2160 = 180n - 360

`180n = 2520

n = 2520 / 180

= 14.

Answer:

12-gon

Step-by-step explanation:

Calculate the perimeter of a rectangle with sides 9cm and 13cm

Answers

9 x 2= 18. 13x 2=26 26+18=44cm

So if 9cm +9cm=18cm then if you do 13cm +13cm=26cm then if you add 18cm + 26cm =44 cm
