Necesito que me resolvais este problema antes de el lunes
POR FAVOR ES URGENTE

A)Longitud de la base del cilindro A=30cm= 2×π×rA>rA= 4,77.

Longitud de la base del cilindro B=40cm= 2×π×rB>rB= 6,37.

Longitud de la base del cilindro C=20cm= 2×π×rC>rC= 3,18.

B)Cilindro B.

C) Va=π×rA^2×40= 2859,22cm^3

Vb=π×rB^2×30= 3824,29cm^3

Vc=π×rc^2×59=1874,38cm^3

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
