Answer:
Prism surface area: 1,271cm
Base area: 66cm
Lateral: 1,139cm
904.32 is the volume.
Volume of sphere
= (4/3)πr³
= (4/3) × 3.14 × (6cm)³
= (4/3) × 3.14 × 6cm × 6cm × 6cm
= 4 × 3.14 × 2cm × 6cm × 6cm
= 904.32 cm³
A because 170.10 and 170.1 are the same. All u do is add zeros to the end, until they have the same number of numbers following the decimal, of the shorter number to see if it is bigger or not.
We have to calculate the height of a cylinder : h2 = ( 45 - 2 · 15 )/ 2 = 15 / 2 = 7.5 mm
Volume of the bottom of the hourglass:V = 1/3 r² π h1 + r² π h2 = = 1/3 · 6² · 3.14 · 15 + 6² · 3.14 · 7.5 = = 1/3 · 36 · 3.14 · 15 + 36 · 3.14 · 7.5 = = 565.2 + 847.8 = 1,413 mm³The rate is 10 π mm³/ sec = 31.4 mm³/secTime = 1,413 : 31.4 = 45 sec.Answer: It will take 45 seconds.
Answer:
The missing side is 18 inches
Step-by-step explanation:
Since in the smaller rectangle the sides are 2.5in x 6in and one side for the larger rectangle is given, you can make an equation.
Then you can cross multiply.
2.5x=45
Divide by 2.5 on both sides.
x= 18
