Answer:
D. 2058.24 in³
Step-by-step explanation:
Let r,h be the radius and height of smaller can and R,H be the radius and height of larger can
Then, R=4r and H=4h
Volume of smaller can=32.16 in³
⇒ πr²h=32.16 in³
Volume of larger can= πR²H
= π(4r²)×4h
= 64πr²h
= 64×32.16 in³
= 2058.24 in³
Hence, correct option is:
D. 2058.24 in³
Answer: Percentage of sales tax will be 5%.
Step-by-step explanation:
Since we have given that
Original amount of a surfboard = $240
Sales tax on a surfboard = $12
So, Percentage of sales tax will be
Hence, Percentage of sales tax will be 5%.
Answer:
B. -2.3
Step-by-step explanation:
It looks like the graph goes down about 7, and over 3, so B makes sense.
(a) put in t = 3 into the r(t) equation provided. Answer will be in gigameters
(b) Use the value of r(t) found in part (a) in the surface area of a sphere equation. S = 4(pi)r² Answer, S will be in units Gm²
(c) This is saying put the equation r(t) into the equation S(r) to make a new equation S(t) or h(t) as they put it.
h(t) = 4(pi)(1.36t + 0.002)²
(d) Put t = 3 into the new equation. Answer will agree with b
4,016
4,000
+
16
Which would equal 4,016
