Volume of the cone is 942 cm³
Step-by-step explanation:
- Step 1: Find the volume of the cone given base area = 78.5 cm² and height = 12 cm
Volume of the cone = Base area × Height
= 78.5 × 12 = 942 cm³
Answer:
7.2 cm
Step-by-step explanation:
First you want to divide 11.5 and 4.6. Which is 2.5. Then divide 18 by 2.5 because you want to do the same to both numbers. Which is 7.2 cm.

Answer:
4/9
Step-by-step explanation:
The scale factor for the linear dimensions of the ball bearings will be the cube root of the volume scale factor:
k = ∛(1.6/5.4) = 2/3
Then the scale factor for the areas will be the square of this scale factor:
ratio of surface area = (2/3)² = 4/9
_____
The area is the product of two linear dimensions, so its scale factor is the product of the linear dimension scale factors. That is, the scale factor for area is the square of the linear dimension scale factor.
Similarly, volume is the product of three linear dimensions, so its scale factor is the cube of the linear dimension scale factor.
Answer:
Rhonda should be thinking that the state income tax deduction was in excess by $4.89
Step-by-step explanation:
The state income tax withholding should have been 21% of the her federal income tax withholding of $122.25
The expected state income tax withholding=21%*$122.25=$25.67
The actual amount deducted for state income tax is $30.56 which translated into excess deduction of $4.89.
The actual deduction was 25% of federal income tax ($30.56/$122.25)
