Question

tolong bantuin ya aku kasih 50 poin hehe​

Answer 1

Penjelasan dengan langkah-langkah:

1) r = 9 cm

r = √(41²-40²) = √(41+40) = √81 = 9

2) s = √(24²+7²) = √625 = 25 cm

Luas selimut = 22/7 x 7 x 25 = 550 cm²

3) s = √(9²+12²) = √225 = 15 cm

Luas selimut = 3,14 x 9 x 15 = 423,9 cm²

4) r = √(26²-24²) = √2(26+24) = √100 = 10 cm

Luas alas = 3,14 x 10² = 314 cm²

5) πrs/πr² = 136π/64π

s/r = 17/8

t = √(17²-8²) = √9(17+8) = √225 = 15 cm

Answer 2

Jawaban:

r² = 41² - 40²

r² = 81

r = ²√81

r = ²√9²

r = 9 cm

--------------------

π × r × s

22/7 × 7 × (√7² + 24²)

22/7 × 7 × 25

22 × 25

550 cm²

==================

π × r × (√9² + 12²)

π × 9 × 15

(9 × 15)π

135π cm²

________________

π × r²

3,14 × 10²

3,14 × 100

314 cm²

———————————

√s² - r²

√(136/8)² - (√64)²

√17² - 8²

√225

15 cm
