Answer:
B.)
Step-by-step explanation:
In the equation 3x+8
3 would be the number of marbles, since x is the weight of the marble, and 8 would be the weight of the empty bucket.
The equation is finding the weight of the bucket, therefore we need to add the weight of the bucket (8) and the weight of the marbles.
A straight like is 180 degrees since you have 38 and wanna find the one beside it to complete the straight line you take 180-38=142 degrees.
First count the fully shaded boxes than count each half knowing two halfs equal one
1)32
2)22
3)22
4)12
Answer is 80pi
Step by step
To find lateral_area = (2 * π * r) * h
Since it’s in term of pi,
(2 x radius x height) pi
2 x 4 x 6 = 48pi
base_area = 2 * π * r²
Since it’s in terms of pi
(2 x r^2)
(2 x 4^2)
= 32pi
Total surface area in terms of pi = 32+48
= 80pi
