Answer:
The diameter is 2
Step-by-step explanation:
We can use a ratio to solve
6 x
------- = --------------
18.84 6.28
Using cross products
6 * 6.28 = 18.84x
Divide each side by 18.84
37.68/18.84 = x
2 =x
Answer: James is right
Step-by-step explanation:
Since they average $685 a day for the month. This means for the month, they'll make:
= $685 × 30
= $20,550
Approximating $20,550 will give $21000 and since James used rounding and estimation to say, "$685 is almost $700 and $700 × 30 days is $21,000. James is quite correct.
Answer:
The answer is A. Objects that have the same size and shape.
Step-by-step explanation:
In geometry, two figures or objects are congruent if they have the same size or shape, or if one has the same shape and size as the mirror image of the other.
Surface area of a cylinder: 2B + Ch
Word form: 2(area of base) + (circumference of base)(height)
Find the numbers you need to plug in to the formula.
Area of base:
2² = <span>12.57 m</span>²<span>
</span>
Circumference of base: 2
2 = 12.57 m
Height: 12 m
Plug these numbers in to the formula.
2(12.57) + (12.57)(12) = 175.98
The SA of the cylinder is 175.98 m².
