Based on the given data, the following formula will be useful;
Area of the base, A = pi*r^2
Lateral Area, A(l) = pi*r*sqrt of h^2 + r^2
Surface Area, A(s) = pi*r*(r+sqrt of h^2 + r^2)
Based on the given area of the base, the radius can be calculated and is equal to 3.9088 in. Based on the given lateral area, the h or the lateral edge can be calculated and is equal to 7.8785 in. Given all the information needed, and directly substituting to the above formula for surface area, SA is equal to 156 in^2 (option D)
Answer:
Jill sold more apples
1 more than Alice
Step-by-step explanation:
Jill sold 40 fruits
Alice sold 40 fruits
15% of Jill's sales is APPLES, that is:
15/100 = 0.15
0.15 * 40 = 6
Jill sold 6 apples.
Now, it is given Alice sold 5 apples.
<em>Who sold more? Of course, Jill.</em>
<em>By how much? 6 - 5 = 1 apple more</em>
Using pythagorean's theorem
a^2+b^2=c^2
a being 3
b being 4
we'll get
9+16=25
where 5 is the hypotenuse and also c.
c^2 = 5^2
The answer is C) 10x + 330 ≤ 600.
We use the ≤ since you are allowed to use the 600th minute.
When we subtract 330 from both sides, it makes a bit more sense
10x ≤ 270
270 is the number of minutes left your plan since you've already used 330, and you have 10 days left in the month.
