Answer:
First, you have to find out the surface area of the box
=> Sbox = 10 x 5 x 2 + 10 x 8 x 2 + 5 x 8 x 2 = 340
Denote Surface area of the ball as Sball, we have:
Sball + Sbox = 352.56
=> Sball = 352.56 - Sbox = 352.56 - 340 = 12.56
From the formula to calculate Sball, we have:
4 x pi x radius^2 = 12.56
=> radius^2 = 12.56/(4 x pi) = 1 (here, pi = 3.14)
=> radius = 1 in

Answer:
21 + 12i
Step-by-step explanation:
Given
(3 - 4i)(1 + 5i) - (2 - i) expand the product of factors
= 3 + 11i - 20i² - 2 + i
= 3 + 11i + 20 - 2 + i collect like terms
= 21 + 12i
1.99p = x
x = total cost
1.99p = 1.99 per pound of grapes.
Answer:
Forced need to stretch 1414 inches = 129830.91 pounds
Step-by-step explanation:
Force ∝ Distance
F = KD where K is constant of proportionality
K = F/D = 6060/66 = 91.818182
Hence Force needed to stretch 1414 inches =
F = 6060/66 x 1414 = 129830.91 pounds
