Find the lateral area of a right circular cone whose radius is 6 feet and height is 8 feet.

Dmitry_Shevchenko [17]

Answer:

we know that

[the lateral area of a right circular cone]=pi*r*l

where

r--------------> the radius of the circle part of the cone

l--------------> the side (slant height) of the cone

r=6 ft

h=8 ft

Step 1

find the slant height of the cone

which is determined by using Pythagoras, since the cross section is a right triangle.

l² = h²+ r²------------> l²=8²+6²-------> l²=64+36---------> l=10 ft

Step 2

find the lateral area

[the lateral area of a right circular cone]=pi*r*l--------> pi*6*10----> 188.4 ft²

the answer is 188.4 ft²

PLEASE HELPPPP!!!!!!

Answer:

C = 3 √ 5

(since 9 is a perfect square), we can simplify radical 45 to 3 times radical 5

B √ 9*5 is true but not simplified.

We need to find a square numbers that divide into 45

We find 9

And show a * b = c

c= 45

so a * b = 9 * 5 = 3√ 5 is how we arrange this to simplify.

Step-by-step explanation:

The list is

1, 4, 9, 16, 25, 36, 49, 64, 81, 100

We see there are 10 perfect squares 1-100

5 are 1-25

then think 6 , 7, 6 , 9 ,10 squared/ if you cant list them too quickly.

Divine bought 96 tins of milk for 3360.00 naira and sold them at 39.00 naira each. calculate his profit on the 96 tins of milk

borishaifa [10]

Based on the calculations, the profit on 96 tins of milk is equal to 384 naira.

<u>Given the following data:</u>

Quantity of milk = 96 tins

Cost price = 3360.00 naira

Selling price = 39.00 naira each.

To calculate the profit on this 96 tins of milk:

<h3>How to calculate profit.</h3>

In this exercise, you're required to determine the amount of profit that was made by Divine for selling 96 tins of milk at 39.00 naira each.

First of all, we would calculate the total sales price or the amount of money he made from selling 96 tins of milk at 39.00 naira each.

$Total\;sales = 96 \times 39$
