Answer: 77.283km^{2}

Step-by-step explanation:

The formula for the lateral area of a cone L.A is:

L.A=\pi r h

Where:

r=10km is the radius of the circular base of the cone

As we know its diameter d=20km, its radius is r=\frac{d}{2}=10km

h=2.46km is the height of the cone

L.A=\pi (10km)(2.46km)

L.A=77.283km^{2} This is the lateral area of the volcano with the shape of a cone

How do you simplify a fraction?
attashe74 [19]
You simplify a fraction by finding it's greatest common factor. A greatest common factor is what both numbers are divisible by. If they can both be divided by two, then you've simplified them a little bit. Keep going until you can't find a common number that can be divided by the two, and you've got your simplified fraction. For example, 10/5 = 1/2 since both 10 and 5 is divisible by 5.

cake batter poured into a pan creates a circular batter pattern whose radius increases at a constant rate of 1 in/sec. at what r
docker41 [41]

Answer:

8 π .

Step-by-step explanation:

radius increases at a constant rate of 1 in/sec.

dr / dt = 1

where r is radius .

radius after 4 sec

r = 1 x 4 = 4 in

area A = π r²

differentiating both sides

dA / dt = 2 π r dr / dt

Putting dr / dt  = 1 , r = 4 in

dA / dt = 2 π x 4 x 1

= 8 π sq in per sec.

Area increases at the rate of 8 π per sec.
