On this question, we can use the order of operations. ( pemdas )
First, we must fill in the missing numbers.
9*21 + (3*3)21 + 12
Start in the parentheses.
(3*3)21 = 9*21 = 189
189+189+12
The rest is just addition now!
189+189+12=390
390 is the correct answer.

I’m pretty sure the answer is C
V = B * h
volume = area of the base * height
The base of this shape is a circle with diameter of 10
the radius (r) is 5
area of circle = pi * r^2 = pi * 5^2 = 25 pi cm^2
the height is 2 meters. The answer needs to be in cm^3
convert m to cm
1 m = 100 cm , 2m = 200cm
A = B * h = 25pi *200= 5000 * 3.14= 15700 cm^3

Total Number of Outcomes=36
The Sum is given as:
![2,3,4,5,6,7\\3,4,5,6,7,8\\4,5,6,7,8,9\\5,6,7,8,9,10\\6,7,8,9,10,11\\7,8,9,10,11,12](https://tex.z-dn.net/?f=2%2C3%2C4%2C5%2C6%2C7%5C%5C3%2C4%2C5%2C6%2C7%2C8%5C%5C4%2C5%2C6%2C7%2C8%2C9%5C%5C5%2C6%2C7%2C8%2C9%2C10%5C%5C6%2C7%2C8%2C9%2C10%2C11%5C%5C7%2C8%2C9%2C10%2C11%2C12)
Multiples of 4 are 4,8 and 12
Number of Multiples of 4=9
Therefore:
Probability that the sum of the numbers on the top of both cubes will be a multiple of 4 =9/36
=1/4.
