What is the volume of the cone?

lina2011 [118]

Answer:

The volume of the cone is 75.36 cm³

Step-by-step explanation:

The rule of the volume of a cone is V = $\frac{1}{3}$ π r² h, where

r is the length of the radius of its base

h is the height of the cone

In the given figure

∵ The length of the radius of the cone is 3 cm

∴ r = 3 cm

∵ The length of the height of the cone is 8 cm

∴ h = 8 cm

→ Substitute the values of r and h in the rule of the volume above

∵ π ≅ 3.14

∵ V = $\frac{1}{3}$ (3.14)(3)²(8)

∴ V = 75.36 cm³

∴ The volume of the cone is 75.36 cm³

Two cars start together in the same direction from the same place. The first goes with a uniform speed of 10 km/h. The second go

Inga [223]

Let the second car meets the first car after n hours.

Second car starts with 8km/h, After succeeding hours his speed increases by 0.5 km.

So, Distance travelled by second car = 8 + 8.5 + 9

..... 8+(n-1) 0.5.....(1)

eqn. (1) sum of n terms Of A.P with first term 8

and common difference 0.5.

Sum of all the terms in equation 1 is also equals to the distance travelled by the first car for n hours, i.e. 10n km .

Now, we have (n/2) {16+(n-1) 0.5} = 10n........(2)

From equation (2) we get, n= 9

Hence, Both the cars will meet after 9 hours.

Hope it helps!
