Answer:
There are 60 total questions on the course exam.
Step-by-step explanation:
Given that:
Number of questions finished by Jasmine = 12
Percentage shown on the bar = 20%
The total number of questions will be 100%, therefore, 20% of the questions are equal to 12.
Let,
x be the total number of questions on the course exam
20% of x = 12

Dividing both sides by 0.2

Hence,
There are 60 total questions on the course exam.
The surface area of a sphere is

where r is the radius;
The circumference is

so that

using this value we can evaluate the surface area of 1 ball as:

For 100 ball you get:
The answer would be <span>27367895.7325</span>
You subtract 7% from 32=29.76
Then you subtract 8% from 29.76=27.379
