Answer:

864ft^3

Step-by-step explanation:

Divide the diameter by 2 to get the radius

12 / 2 = 6

Then solve the volume equation using 3 for pi.

4/3 * 3 * 6^3

4 * 6^3

4 * 216 = 864

Maureen went on a 3 day 50 mile trip. the first day she biked 17 7/8 miles . the second day she biked 18 5/7 miles. How many mil

Inessa [10]

To find the miles for 3rd day, we take away the miles she biked for the first two day from the total.

$50 - 17 \dfrac{7}{8} - 18\dfrac{5}{7}$

$=50 - 17 \dfrac{7 \times 7}{8 \times 7} - 18\dfrac{5 \times 8}{7 \times 8}$

$= 48 \dfrac{112}{56} - 17 \dfrac{49}{56} - 18\dfrac{40}{56}$

$= 13 \dfrac{23}{56} \text { miles }$

Help needed for this question please

enyata [817]

Answer:

Step-by-step explanation:

Area of the shaded region = Area o triangle - Area of the semicircle

Area of triangle = 1/2 * base * height

Area of triangle = 1/2 * 6 * 6

Area of triangle = 3 * 6

Area of triangle = 18sq. m

Area of semicircle = πr²/2

r is the radius = 2m

Area of semicircle = π(2)²/2

Area of semicircle = 2(3.14)

Area of semicircle = 6.28sq. m

Area of the shaded region = 18 - 6.28

<em>Area of the shaded region = 11.72sq.m</em>
