Ответ:
Sphere Vol = 4/3Pi radius^3
Give the 4/3Pi bit a constant - 'C'
Vol = C x radius^3
V1 = C 3^3 = 27C
V2 = C 5^3 = 125C
New Volume = 27C + 125C = 152C
Aproximate radius = cube Root 152 = Approx 5.3
(5 cubed = 125, 6 cubed = 216)
Ответ:
$35.66
Step-by-step explanation:
$17.99 shirt x 20% discount = $3.60
$17.99 reg price tshirt - $3.60 discount = $14.39 per shirt
$14.39 per shirt x 3 shirts = $43.17 before taxes
$43.17 sale price for 3 shirts - $10 coupon = $33.17 base price
$33.17 x 7.5% sales tax = $2.49
$33.17 + $2.49 = $35.66 total
