Answer:
358
Step-by-step explanation:
Volume = length x width x height or V = lwh as a formula if you will.
Let's substitute what we know into the formula:
100 = 4(5)h multiply the 4(5) on the right side
100 = 20h divide both sides of the equation by 20
5 = h
the height of the rectangular box is 5 feet
Answer)
1 obtuse angle and 2 angles with the same measure of 40
1 right angle and 2 congruent acute angles
Answer:
f(x)=3 x (4)^x
Im pretty sure the answer is A.
Hope this is right .-. Sorry if its not
Answer:
A = 9π cm²
Step-by-step explanation:
Given that area (A) varies directly with r² then the equation relating them is
A = kr² ← k is the constant of variation
To find k use the condition A = 4π when r = 2 , then
4π = k × 2² = 4k ( divide both sides by 4 )
π = k
A = πr² ← equation
when r = 3 , then
A = π × 3² = 9π cm²
