Answer:
B
Step-by-step explanation:
The formula is (4/3) *pi*r^2, which means that it's 42^2 * pi * 4/3 = 7385.28
Answer: C
Step-by-step explanation: The X angle and the 76 degrees form a supplementary angle. All supplementary angles have a total degree of 180 degrees (a+b=180). We already know one angle degree is 76. This makes 76+x=180. To solve this, subtract 76 from 180. This gives you x= 104 degrees
I assume that the question is: what is this nunber?
we write this like this:
The sum of 14 and a number is 14+x
we know that this equals 17, so: 14+x=17.
Let's substract 14 from both sides:
x=17-14
x=3
so the number is 3.
