A cone has a circular base of radius 8m. Given that the total surface area of the cone is 350m^2, find the slant height

Gnom [1K]

<h3>Hello There!!</h3><h3><u>Given</u></h3>

Radius of Circular Base Of Cone= 8m

Total Surface Area= 350m²

<u>Considering</u> Slant Height as l

<h2><u>Solving</u></h2>

Total Surface Area= Curved Surface Area of Cone+ Area of circular Base

i.e.,

$350 { \text{m}}^{2} = \pi \times r \times l + \pi \times {r}^{2}$

$350 = \pi \times r(l \times r) \\ \\ \implies 350 = 3.142 \times 8(l + 8) \\ \\ \implies \frac{350}{3.142 \times 8} = l + 8 \\ \\ \implies 13.924 = l + 8 \\ \\ \implies l = 13.924 - 8 \\ \\ \therefore l = 5.924 \: \text{cm}$

So, Slant Height= 5.924 cm

The Earth’s total diameter is 12700 kilometers, with the solidified, ocean-covered crust that is at its thickest 35 kilometers w

Basile [38]

Answer:

The correct answer is 0.0667 centimeters.

Step-by-step explanation:

Diameter of earth is 12700 kilometers.

Width of the solidified ocean crust is 35 kilometers.

Ratio between the diameter of the earth and the solidified crust is $\frac{12700}{35}$ .

Now the earth is shrunken to a size of a basketball with the diameter as 24.2 centimeters. Let the thickness of the Earth's crust in this model be x centimeters.

Ratio between the diameter of the model earth and the solidified crust is $\frac{24.2}{x}$ .

But this ratio of the real Earth and its model must be equal.

∴ $\frac{12700}{35}$ = $\frac{24.2}{x}$

⇒ x = 0.0667 centimeters.

Find sinx given cos2x=5/9

Diano4ka-milaya [45]

Answer:

sinx = √2/3

Step-by-step explanation:

cos2x = 1-2sin²x

5/9 = 1-2sin²x

2sin²x =1-5/9

2sin²x = 4/9

sin²x = (4/9)/2

sin²x = (4/9)*(1/2)

sin²x = 2/9

sinx = √2/3

Uncle John has 30 lemon trees and 36 lime trees to plant on his grove. He would like to plant the trees in rows where each row h

Rufina [12.5K]

Answer:

Step-by-step explanation:

this question is basically asking you to find the HCF of 30 and 36

step 1 : draw prime factor tree diagrams and write the numbers out as the product if their prime factors

step 2: multiply the prime factors they have in common

30 = 2 x 3 x 5

36 = 2 x 2 x 3 x 3

HCF = 2 x 3 = 6
