Question

Calculate the total surface of a solid cone or vertical height 24cm and base diameter 14cm use,the value 22/7 for pier

Answer 1

Diameter=2r

r=7

L²=r²+h²

L²=7²+24²=625

L=√(625)=25

You know l=25 ,r=7 and h=24

Plug into the formula above and you done

recall that TSA==πrl+πr²=πr(l+r)

Answer 2

total I assume includes the base

so
pi r^2 + pi r L = pi r (r+L)
where L is the slant height =sqrt(r^2+h^2)
here r = 7 cm and h = 24 cm
L= sqrt( 49 + 576) = sqrt (625) = 25 that is handy :)
so
pi r (r+L) = pi (7)(7+25)

Answer 3

i have to make up a story using $100 bills, nine $10 bills,

and twenty $1 bills. but in division. what story can i make up?

Answer 4

TSA= πr(l + r)

Diameter=14, therefore
Radius = d/2= 14/2= 7.
Length(l²)= r²+h²
L²= 7²+24²
L=√625= 25.
Since l=25, r=7, h=24
Therefore, we input it in the formula
TSA=πr(1+r)
=22/7 × 7 (25+7)
=22(32)
=704

Answer 5

Yes

Answer 9

Calculate the total of a solid cone of vertical height 24centimetres and base diameter of 10 cm

Answer 10

[AI-generated answer — Bot]

To calculate the total surface area of a solid cone, we need to know the slant height of the cone. However, the information given only includes the height and base diameter.

To proceed, we can use the Pythagorean theorem to find the slant height.

Using the formula for the slant height of a cone:
l = √(r² + h²)

Given that the base diameter is 10 cm, the radius (r) will be half of that:

r = 10 cm / 2 = 5 cm

Plugging these values into the formula for the slant height, we have:

l = √(5² + 24²)
= √(25 + 576)
= √601
≈ 24.5 cm

Now that we have the slant height, we can calculate the total surface area of the cone:

TSA = πr(r + l)

TSA = π * 5 cm * (5 cm + 24.5 cm)
≈ π * 5 cm * 29.5 cm
≈ 461.925 cm²

Therefore, the total surface area of the cone is approximately 461.925 square centimetres.
