Would really appreciate some help

Hi,

a) 6s² = 6 * 5² = 6 * 25 = 150

b) πr² = π * 2.5² = pi * 6.25 ≈ 19.6

Rounded to one decimal place. Notice that we don't use the equal symbol here but the approximation one.

c) a² + b ² = 3² + 4² = 9 + 16 = 25

d) πr²h = π*2.3²*5.2 = π * 27.508 ≈ 86.4

Rounded to one decimal place.

e) (4/3) π r^3 = (4/3) π *1.5^3 = π * 4.5 ≈ 14.1

Rounded to one decimal place

f) x² - 2x - 24 = (-6)² - 2(-6) - 24 = 36 + 12 - 24 = 48 - 24 = 24

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

7

step-by-step explanation:

the answer would be 7
