In his garden, Jim is using cone-shaped planters for his hanging plants. Each planter has a diameter of 8 inches and a height of 13 inches. He has 6 planters, and wants to fill each planter Syntax error from line 1 column 49 to line 1 column 73. Unexpected 'mathsize'. Of the way with soil. What is the total volume of soil Jim will need for his hanging plants?

979.68 in^3

Step-by-step explanation:

Here is the complete question

In his garden jim is using cone shape planters for his happing plants has a diameter of of 8 inches and a height of 13 inches he has 6 planters and wants to fill each plamter 3/4of the way with soil what is the total volume of soil jim will need for his hanging plants

total volume of soil needed = 3/4 x volume of the 6 planter

volume of the 6 planters = volume of a planter x 6

volume of a planter = volume of a cone

Volume of a cone = 1/3(nr^2h)

n = 22/7

r = radius = 8/2 = 4

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

h = height

1/3 x 4^2 x 13 x 3.14 = 217.71

6 planters = 217.71 x 6 = 1306.24

3/4 x  1306.24 = 979.68 in^3

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
