Area of a Circle= (pi)(radius) squared
Find the area of each cake, then subtract the difference between those 2 answers to find the difference in area. Also remember the problem gives you diameter, but the area formula requires radius so you must divide the diameter by 2.
Vanilla Cake Area
A= (3.14)(8/2) squared
A=(3.14)(4) squared
A=(3.14)(4*4)
A=(3.14)(16)
A=50.24 inches
Chocolate Cake Area
A=(3.14)(10/2) squared
A=(3.14)(5) squared
A=(3.14)(5*5)
A=(3.14)(25)
A=78.5 inches
Difference in Area
Chocolate Area - Vanilla Area
= 78.5 - 50.24
= 28.26 inches difference

Answer:
79
Step-by-step explanation:
Let's say that N is the number of cards.
So the first step is N+5, because dan bought 5 new cards.
Next his dog ate half the collection, so the 2nd piece of the problem is
The last step is to now make it an equation. Because there are now 46 cards left, =42.
Now solve for N which is N+5=84=> N=79

Answer:
it's 166.277
Step-by-step explanation:
i took the test & got it right
1800 - 1350= 450 3 months after the purchase he payed $450
450/3= $150 per month
1350 - 1050= 300 5 months AFTER THE PURCHASE he payed $300
300/2= $150 per month
^after 2 more months he payed $300^
$150 per months
Equation: (initial amount) - (150)M
M= amount of months after purchase
B = 1800 - 150M
Answer:
5.2 seconds
Step-by-step explanation:
Traveling straight down: 90 * 3.5 = 315 feet down
Traveling up: 30 * 2.2= 66
315-66= 249
249/48= 5.1875 seconds
5.2 seconds <- rounded
