Answer:
8 meters.
Step-by-step explanation:
Let the 2 radii be x and 2x, then
π x^2 + π (2x)^2 = 80π
π x^2 + π 4x^2= 80π
x^2 + 4x^2= 80
5x^2 = 80
x^2 = 16
x = 4.
So the radius of the larger circle = 2*4 = 8 m.
26=w-12
+12 +12
38=w
That is your answer
Step-by-step explanation:
Assuming that the total stamp is x
According to the question
Izzati's stamps is 1/4
Ailing's number of stamps is 1/8
X= 1/4 x 1/8 = 5/8 - the remaining stamps.
Rina’s number of stamps is 7/10 x 5/8 = 35/80 x
5/8 x 35/80 = 15/80 - (Susan's stamps)
According to the question
15/80 = 42
X: 224
the total number of stamps originally is 224.

To answer this question you need to know the conversion rate from kilometer into cm. For every kilometer it would be 1000m and for 1m it will be 100cm. That mean 1km is equal to 100,000cm or 10^5 cm. Then the answer would be:
(3.34 * 10^5 cm) * (1km/10^5cm)= 3.34km
