Step-by-step explanation:you would divide 15 by 2 and 1/2
Convert 4 seconds to minutes, which would be 4/60
then divide 7 ft by 4/60 minute, and you get 105.
fyi, im not 100% sure this is correct
Minus 1/4 on both sides to get s= 12 1/4

Answer:
The surface area of the red sphere is 452.4 cm²
Step-by-step explanation:
The question here is easy to calculate provided you understand it and apply the formula necessary for deriving the answer and it says that two spheres are similar. The surface area of the blue sphere is 9160.9 square centimeters with a radius of 27cm. What is the surface area of the red sphere with a radius of 6cm
Surface area of a sphere is given as 4 × pi × r²
And if we have he radius as 6 cm,we can then input the figured so as to get the surface area of this sphere.
Remember that pi= 22/7 or 3.142
4 × 22/7 × 6² = 452.4 cm²
