d. t = √(s² - r²)
t = √(25² - 7²)
t = √(625 - 49)
t = √576 = 24

Lp = πr(r + s)
Lp = 22/7 x 7(7 + 25)
Lp = 22(32)
Lp = 704 cm²

V = ⅓ πr²t
V = ⅓ x 22/7 x 7² x 24
V = 1232 cm³

e. r = √(s² - t²)
r = √(4² - 3²)
r = √(16 - 9)
r = √7

Lp = πr(r + s)
Lp = 3,14 x √7(√7 + 4)
Lp = 8,31(6,65)
Lp = 55,23 cm²

V = ⅓ πr²t
V = ⅓ x 22/7 x (√7)² x 3
V = 22 cm³

f. t = √(s² - r²)
t = √(13² - 5²)
t = √(169 - 25)
t = √144 = 12

Lp = πr(r + s)
Lp = 3,14 x 5(5 + 13)
Lp = 15,7(18)
Lp = 282,6 cm²

V = ⅓ πr²t
V = ⅓ x 3,14 x 5² x 12
V = 314 cm³
