So the radius is 5 cm
and we are given the volume at 225 cm³
now breakdown the volume formula for a cone which is V equals 1/3 Bh
b= pi r squared

now substitute everything in
225 equals 1/3 pi(5)^2 Times h
since we don’t know H that is what we’re solving for

225= 1/3 pi(25) times h
multiple 3/1 on both sides to cancel the 1/3
675= 25(3.14) times h
675= 78.5 (h)
h= 675/78.5
h=8.60 cm

A shop sells three types of boots sales are usually in the ratio of 6:2:3 last month 24 football boots were sold how many boots

Sonja [21]

The three types of boots are sold in the ratio 6:2:3.

This ratio may be written as 6x:2x:3x where x is a variable.
When 24 boots are sold, then
6x + 2x + 3x = 24
11x = 24
x = 24/11 = 2.18

Because we do not have fractional boots, x = 2.
Total boots sold = 6*2 + 2*2 + 3*2 = 12 + 4 + 6 = 22

Mr. Richard owns an orchard that has a rectagular fence . The orchard is 36 yards long and 18 yards wide . if he walks across th

Sergio [31]

Answer:

40.2 Yards

Step-by-step explanation:

To find the diagonal length of the orchard, we need to use the Pythagorean Theorem. The formula of the Pythagorean Theorem is:

c²= a² + b²

a = 36 Yards

b = 18 Yards

Now let's plug in our values to the formula.

c² = a² + b²

c² = 36² + 18²

c² = 1296 + 324

c² = 1620

Now to find the value of c we need to get the square root of both sides.

$\sqrt{c^{2}}=\sqrt{1620}$

c = 40.2

So the diagonal length of Mr. Richard's orchard is 40.2 Yards.

Find the area and perimeter. The area is ... and the perimeter is ...

Schach [20]

Answer:

Area: 6a^2

Perimeter: 12a^2

Step-by-step explanation:

To find the area of a triangle, use the formula A=1/2 b*h. The base is 3a^2 and the height is 4a^2.

A= 1/2 (3a^2)(4a^2)

A = 1/2 (12a^4)

A = 6a^4

To find the perimeter of the triangle, add each of the sides of the triangle. The third side, the hypotenuse, can be found using Pythagorean theorem.

$a^2+b^2=c^2\\(3a^2)^2+(4a^2)^2 = c^2\\(9a^4)+(16a^4)=c^2\\25a^4=c^2\\5a^2=c$

Now add each of the sides: 3a^2 + 4a^2 +5a^2 = 12a^2
