Answer:
Radius of sphere is 3 units.
Step-by-step explanation:
Volume of sphere is given by 
surface area of sphere is given by 
where r is the radius of the sphere.
Given that
The number of cubic units in the volume of a sphere is equal to the number of square units in the surface area of the sphere.
we equate formula of Volume of sphere and surface area of sphere
assuming r as the radius.
thus,

Thus, radius of sphere is 3 units.
Answer:
Approximately 54.54% of race happened in the first week.
Step-by-step explanation:
We are given the following in the question:
Length of bike race in three weeks = 2,200 miles
Race covered in first week = 1,200 miles
Percentage of race covered in first week =

Thus, approximately 54.54% of race happened in the first week.
It is:
40+1+0.3+0.02=41.32
Answer:
Rs 448
Step-by-step explanation:
400 × 1.12 = 448
this a 12 % increase
Answer:
A: x‒axis: minutes in increments of 5; y-axis: temperature in increments of 1
Step-by-step explanation:
Let the x-axis represent the minutes
Let the y-axis represent the temperature
Now, from the values given us in minutes, we can see that the difference between the values are Increasing at constant rate of 5 minutes .
Thus, minutes increment on the x-axis is 5.
Now,for the y-axis, the increment is not constant as it fluctuates.
Thus, we cannot use 5 like we did for the x-axis. Rather, the most appropriate temperature increment to be used on this y-axis for ease of locating the points will be 1.
