Answer:

Question 1 )

given ,

height of cylinder = 9 cm

diameter of cylinder = 10 cm

\dashrightarrow \: radius =  \frac{10}{5}  \: cm \\

now ,

Volume \: of \: cylinder = \pi \: r {}^{2} h \\  \\ substitutng \: the \: values \: of \: h \: and \: r \:  \\  \\ \dashrightarrow \:  \pi \:   \times  (\frac{10}{2} ) {}^{2}  \times 9 \\  \\ \dashrightarrow \: \pi \:  \times 25 \times 9 \\  \\ \dashrightarrow \: 225\pi \: cm {}^{3}

therefore ,

<u>option </u><u>(</u><u>C)</u> is correct.

Answer this question correctly please and then I’ll mark you as a brainliest!

Answer:


Step-by-step explanation:

1) 2 - (- 8) = 2 + 8 = 10


2) 2/5 + (- 1/5) = 2/5 - 1/5 = 1/5


3) We can find the common denominators through the least common multiple between the denominators:


4,12 | 2

2, 6 | 2

1, 3 | 3

1, 1 (2 × 2 × 3 = 12)


Then, 12 is the least common denominator.


4) 8 (1/4) + 10 (2/5) + 7 (5/8)

8 (1/4) = 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 1/4 = 33/4


10 (2/5) = 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 2/5 = 52/5


7 (5/8) = 8/8 + 8/8 + 8/8 + 8/8 + 8/8

+ 8/8 + 8/8 + 5/8 = 61/8


33/4 + 52/5 + 61/8


Employing the least common denominator:


4, 5, 8 | 2

2, 5, 4 | 2

1, 5, 2 | 2

1, 5, 1 | 5

1, 1, 1 (2 × 2 × 2 × 5 = 40)


(40 ÷ 4 × 33)/40 + (40 ÷ 5 × 52)/40 + (40 ÷ 8 × 61)/40

330/40 + 416/40 + 305/40

1051/40


This person ran about 26 Miles


I hope I helped you.
