4. If the sides of a square measure 9V3 units, then find the length of the diagonal.

Nitella [24]

Answer:

Step-by-step explanation:

To find the diagonal, use Pythagorean theorem,

diagonal² = side² + side²

= (9√3)² + (9√3)²

= 9²(√3)² + 9²(√3)²

= 81*3 + 81*3

= 243 + 243

= 486

diagonal = √486 = 22.05 units

Answer:

4) 1400 $in^3$

5) 304 $\Pi$ or 954.56 $yd^3$

6) 315 $ft^2$

Step-by-step explanation:

$4)$

$V = \frac{lwh}{3} = \frac{20*20*10.5}{3} = \frac{4200}{3} = 1400$

$5)$

$A = \Pi(\frac{D}{2})^2 = \Pi(\frac{8}{2})^2 = \Pi*4^2 = 16\Pi$

$V = A * h = 16\Pi * 19 = 304\Pi = 304 * 3.14 = 954.56$

$6)$

$h^2 = 8^2 + 8^2 => h^2 = 64 + 64 = 128 => h =\sqrt{128}$

$A_1 = 2(\frac{8*\sqrt{128}}{2}) = 8*\sqrt{128} = 32 = 90.5$

$A_2 = 2(14 * 8) = 2*112 = 224$

$A = A_1 + A_2 = 91 + 224 = 315$

The diameter of a circle is 12 miles, what is the length of the 180 degree arc in the simplest form?

laila [671]

9514 1404 393

Answer:

6π ≈ 18.8 miles

Step-by-step explanation:

The full circumference of a 12-mile circle is ...

C = πd

C = π(12 mi)

So, half the circumference of the circle is ...

arc length = 1/2C = (12π mi)/2 = 6π mi ≈ 18.8 mi
