Answer:
300 squared feet.
Step-by-step explanation:
Area of a rectangle = length × breadth = 20 × 15 = 300 squared feet.
Answer:
cubic inches
Step-by-step explanation:
Diameter is increasing at 3 inches more than time, When t = 3
Diameter (d) = 3+3 = 6
d = 6
Radius is HALF of diameter, so
r = 6/2 = 3
Now, the volume of a sphere is given by the formula:

Putting r = 3, we get:

The volume would be 36π
He might be 6 now.
hope this helped :)
plzz tell me if I was wrong
First you will divide 525 by 100. Then you multiply your answer by 4. That will equal 21
