Ответ:
The factor is 7/8
Step-by-step explanation:
Ok, we know that Sphere A as a radius of 24 cm, and sphere B has a diameter of 42 cm.
We want to find the factor which multiplied by the radius of sphere A gives us the radius of sphere B.
First, let's find the radius of sphere B.
We know that Diameter = 2*Radius.
So the radius of sphere B is equal to the diamater divided by 2.
rB = 42cm/2 = 21cm
now, let's find the number x that:
24cm*x = 21cm
x= 21cm/24cm = 21/24
now, we can divide numerator and denominator by the same number, in this case 3, and get:
x = 21/24 = (21/3)/(24/3) = 7/8
x = 7/8
So the factor is x= 7/8, the second option.
