1. 8.2•8.2= 67.24.
2. 0.5(9•11)= 49.5.
3. pi•(17/12)^2= about 289/144pi.
4. 3.75•7.6= 28.5.
5. (42•20)+(10•22)= 840+220= 1,060.
6. 0.5(10.667•3.2)+(10.667•15)= 170.667+160= 330 and two thirds.

For the first one each side would be 2.05. Because 2.05 x4 = 8.2. I hope this helps.

r = 2 inches

total h of the cylinder = 6+6+6 = 18 inches

$SA = 2\pi {r}^{2} + 2\pi \: rh$

$= 2\pi \: r(r + h)$

$= 2 \times 3.14 \times 2(2 + 18)$

$= 2 \times 3.14 \times 2 \times 20$

$= 251.2square \: inches$

The position function for a free-falling object is s(t) = -16t^2 + vt +5. A ball is thrown upward from the top of a 400-foot bui

mixer [17]

Answer:

6.21 seconds

Step-by-step explanation:

The position function of a free-falling object is,

$s(t) = -16t^2+v_0t+s_0$

Where,

$s_0$ = initial height of the object,

$v_0$ = initial velocity of the object,

Here,

$s_0=400\text{ feet}$

$v_0=35\text{ feet per sec}$

Hence, the height of the ball after t seconds,

$s(t)=-16t^2+35t+400$

When s(t) = 0,

$\implies -16t^2+35t+400=0$

$t=\frac{-35\pm \sqrt{35^2-4\times -16\times 400}}{2\times -16}$

$t=\frac{-35\pm \sqrt{1225+25600}}{-32}$

$\implies t\approx -4.02\text{ or }t\approx 6.21$

∵ Time cannot be negative,

Hence, after 6.21 seconds the ball will reach the ground.

bulgar [2K]

Answer:

60 types of cotton chambray shirts can be produced

Step-by-step explanation:

The shirt comes in the following colors: blue, stone, rust, green, plum, and indigo

Number of colors the shirt comes in = 6

The shirt comes in the following sizes: small (S), medium (M), large (L), extra large (XL), and extra extra large (XXL)

Number of sizes the shirt comes in = 5

The shirt comes in the following styles: short sleeves or long sleeves

Number of styles the shirt comes in = 2

Total number of cotton chambray shirts that can be produced are:

No. of colors * No. of sizes * No. of styles

6 * 5 * 2

60 shirts

So, 60 types of cotton chambray shirts can be produced from the given options of colors, sizes and styles.
