Ken and leah. are trying to solve a science homework question. they need to find out how much a rock that weights 4 pounds on earth would weight on venus. they know they can multiply the amount the rock weights on earth by 0.91 to find its weight on venus. select the two partial products ken and leah would need to add to find the product of 4 and 0.91.

The partial products are 3.6 and 0.04.

Step-by-step explanation:

The partial products are found by multiplying each place in 0.91 by 4.

The first digit, 9, is in the tenths place; this makes its value 0.9.  Multiplying this by 4 gives us

0.9(4) = 3.6.

The second digit, 1, is in the hundredths place; this makes its value 0.01.  Multiplying this by 4 gives us

0.01(4) = 0.04

Adding these together gives us our product:

3.6+0.04 = 3.64

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
