Find the area of a circle with a diameter of 14 meters. Round your answer to the nearest hundredth of a square meter.

Jlenok [28]

To find the area of the circle:

⇒ need to know the formula: $\pi r^{2}$

r: radius or half of diameter's length ⇒ 7 meters

Let's calculate:

$Area = \pi (7)^2=49\pi =153.9380m^3$

The problem asks us to round to the nearest hundreth:

$Area = 153.94m^3$

Answer: $153.94m^3$

Hope that helps!

Please help me solve this

Nataly_w [17]

Answer:

x = 24

Step-by-step explanation:

using the rule of exponents

$a^{m}$ × $a^{n}$ = $a^{(m +n)}$

consider left side

$5^{\frac{x}{6} }$ × $5^{\frac{x}{2} }$

= $5^{\frac{x}{6} }$ × $5^{\frac{3x}{6} }$

= $5^{\frac{4x}{6} }$

then

$5^{\frac{4x}{6} }$ = $5^{16}$

since the bases on both sides are equal, both 5 then equate exponents

$\frac{4x}{6}$ = 16 ( multiply both sides by 6 )

4x = 96 ( divide both sides by 4 )

x = 24

Answer:

Step-by-step explanation:

since y and x vary directly the equation relating them is

y = kx ← k is the constant of variation

to find k use any ordered pair from the list given

using x = 4 when y = - 2, then

k = $\frac{y}{x}$ = $\frac{-2}{4}$ = - 0.5 → B
