Answer:

circumference = 37.68 (37.7 if you're rounding it)

Area = 113.04 (113.1 if you're rounding it)

Step-by-step explanation:

The formula for circumference is C=2πr (2 times pi times radius)

If the diameter is 12, the radius is 6.

2 x 3.14 x 6 = 37.7

The formula for area is A=πr2 (pi x radius to the second power)

The radius is 6. Six to the second power is 36.

36 x 3.14 = 113.04

Vera_Pavlovna [14]

Answer:

The way a proportion is set is as follows;

$\dfrac{1 \ inch}{200 \ miles } = \dfrac{4 \ inches}{ Distance \ from \ Rio \ de \ Janeiro \ to \ San \ Jose}$

The Distance from Rio de Janeiro and San Jose Costa Rica is then found as 800 miles

Step-by-step explanation:

The dimension of the distance between Rio de Janeiro and San Jose Costa Rica = 4 inches

The map scale = 1 inch to 200 miles

To figure out how many miles it is or the actual distance from Rio de Janeiro and San Jose Costa Rica, we have;

$\dfrac{1 \ inch}{200 \ miles } = \dfrac{4 \ inches}{ Distance \ from \ Rio \ de \ Janeiro \ to \ San \ Jose}$

Therefore, we have;

(4 inches × 200 miles)/(1 inche) = Distance from Rio de Janeiro and San Jose Costa Rica

Which gives;

Distance from Rio de Janeiro and San Jose Costa Rica = 800 miles.
