Answer:
80ft²
Step-by-step explanation:
Given in the question,
radius of cone's base = 8ft
cone's base = base of triangle
height of cone = 10 ft
height of cone = height of triangle
<h3>Area of triangle </h3>
Area = 1/2(h)(b)
here h = height of triangle
b = base of triangle
A = 1/2(8)(10)
A = 40ft²
Since the section is 2 similar triangles back to back around the vertical centre so the area cross sectional area of triangle form in the cone is 2(40)ft² = 80ft²
Answer:
1. 10 inches 2. $7.70
Step-by-step explanation:
For number one they are simply multiplying the width by 2 and for the length, it would be 5 times 2 and you'll get 10 inches.
For number 2, you had to do 21 divided by 3 and get 7. Then find 10% of 21 which is 2.10. Then 2.10 divided by the three people is 0.7. So add 7 and .7 together and get $7.70
