Answer:
27.93 square yard
Step-by-step explanation:
For semicircle:
Radius (r) = 7 yards
For Triangle:
b = 2r = 2*7 = 14 yd
h = 7 yard
Area of shaded region = Area of semicircle - Area of triangle
![= \frac{1}{2} \times \pi {r}^{2} - \frac{1}{2} \times b \times h \\ \\ = \frac{1}{2} \times 3.14 \times {7}^{2} - \frac{1}{2} \times 14\times 7 \\ \\ = \frac{1}{2} \times 3.14 \times 49 - \frac{1}{2} \times 98\\ \\ = 3.14 \times 24.5 - 49 \\ \\ = 76.93 - 49 \\ \\ = 27.93 \: {yd}^{2} \\](https://tex.z-dn.net/?f=%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20%5Cpi%20%7Br%7D%5E%7B2%7D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20b%20%5Ctimes%20h%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%203.14%20%5Ctimes%20%20%7B7%7D%5E%7B2%7D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%2014%5Ctimes%207%20%5C%5C%20%20%5C%5C%20%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%203.14%20%5Ctimes%20%2049%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%2098%5C%5C%20%20%5C%5C%20%20%3D%203.14%20%5Ctimes%2024.5%20-%2049%20%5C%5C%20%20%5C%5C%20%20%3D%2076.93%20-%2049%20%20%5C%5C%20%20%5C%5C%20%20%3D%2027.93%20%5C%3A%20%20%7Byd%7D%5E%7B2%7D%20%20%5C%5C%20)
Answer:
48 feet
Step-by-step explanation:
Distance = rate × time
d = 12 ft/min × 4 min
d = 48 ft
The diver will be 48 feet below the surface.
3.5 is the same thing as 3 1/2
5.5 is the same thing as 5 1/2
3.5 walls/1 day
3.5 walls x 5.5 days = 19.25 walls
Answer:
x=5 miles
Step-by-step explanation:
first you have to get his constant speed or his rate
rate = time / distance
so in this case 27/3 which equals 9,
1 mile = 9 minutes
then, you would set up your equation
9 minutes = 1 mile
45 minutes = x miles
cross multiply , 45 * 1= 45 , then divide by 9
x = 5 miles
