Ad libitum [116K]

Answer: 200.96

A - C/r, d = 16 ⇒ r = 8

A = (16π/2) (8)

<h3><u>Given</u>:-</h3>

Volume 6,900 cm^3
Length = 23 cm
Width = 10cm

Height of box ??

<h3><u>Solution</u>:-</h3>

$\\\diamond{\underline{\underline{\sf {\;\; Calculating\; Height\; of \; box :-}}}}\\$

$\\ \pink \star \: \: {\underline{\boxed {\bf{ Volume_{ \red{ \{Rectangle \}}} \: = l \times w \times h }}} }\; \red\bigstar \\$

Where,

» l denotes Length
» w denotes Width
» h denotes Height

$\\ \sf \implies \: {Volume_{ \red{ \{Rectangle \}}} \: = l \times w \times h} \\$

$\\ \sf \implies \: { 6,900 \: = \: 23 \: \times \: 10 \: \times h} \\$

$\\ \sf \implies \: { 6,900 \: = \: 230 \: \times \: h} \\$

$\\ \sf \implies \: { \: h \: = \: \frac{6900}{230} \: } \\$

$\\ \sf \implies \: { \: h \: = \: 30 \: {cm }^{3} \: } \\$

$\\ \implies{\underline{\boxed{\frak { Height = 30 \: cm^3 }}}} \; \purple\bigstar \: \\$

$\\\qquad \rule{120pt}{3pt}\\$

Therefore , the Volume of the Box is 30 cm ³.

Rina8888 [55]

Answer:

10 hours

Step-by-step explanation:

Given:

Average speed of submarine = 10 mph

Speed of carrier in the opposite direction = 20 mph

Distance between the submarine and carrier = 300 mi

To find:

The time taken so that the distance between them is 300 mi ?

Solution:

The relative speed when they are traveling in opposite direction = 10+20 = 30 mph

Formula:

$\text{Time }=\dfrac{\text{Distance Traveled}}{\text{Speed}}$

$\text{Time }= \dfrac{300}{30} = \bold{10\ hours}$

So, the answer is <em>10 hours</em>.
