Given:
Cylinder: radius = 8 yd; height = 4 yd
Surface Area = 2 π r h + 2 π r²
SA = 2 * 3.14 * 8 yd * 4yd + 2 * 3.14 * (8yd)²
SA = 200.96 yd² + 401.92 yd²
SA = 602.88 yd²
Volume = π r² h
V = 3.14 * (8yd)² * 4yd
V = 803.84 yd³
Dimension is cut in half. radius = 4yds ; height = 2yds
S.A = 2 * 3.14 * 4yd * 2yd + 2 * 3.14 * (4yd)²
S.A = 50.24 yd² + 100.48 yd²
SA = 150.72 yd²
V = 3.14 * (4yd)² * 2yd
V = 100.48 yd³
SA = 602.88 yd² - 150.72yd² = 452.16 yd²
V = 803.84 yd³ - 100.48 yd³ = 703.36 yd³
I think it would be 195 or it might be 195 or it might be 195 or it might be 195
Answer:
C. P69,256.82
Step-by-step explanation:
We know that,
The amount formula in compound interest is,

Where, P is the principal amount,
are the annual rate for the different periods,
are the number of year for different periods,
are the number of periods,
Given,
A = P 200,000,
,
,
,
,
, 
Thus, by the above formula the final amount would be,




Option C is correct.
The answer would be A,B,A
Answer:$378.95
Step-by-step explanation:
Change it all to fractions.
3/10 of her salary on rent
2/5 of her salary on entertainment
1/4 of her salary on living expenses.
Add them
3/10 + 2/5 + 1/4 = 6/20 + 8/20 + 5/20 = 19/20*S
(19/20)*S = 7200
S = 7200*20/19
------
She saved the remaining 1/20 of S = 7200/19
saved =~ $378.95
