Answer:
V = 1436.76
Step-by-step explanation:
<u>Formula:</u>
V = 4/3πr³
<u>Given:</u>
r = 7
<u>Work:</u>
V = 4/3πr³
V = 4/3π(7³)
V = 4/3π(343)
V = 1436.76
Answer:
21
Step-by-step explanation:
Don't overthink it darling, just plug in the numbers to the equation. When you do that, you get 3+(5 + 4)(8 - 6). You add the 5 and 4 and subtract the 8 and 6. Your equation now is 3+9*2. Being there is no sign between the two )( it means your multiplying. So you do 9*2 and you get 18+3 and you get your answer of 21.
Answer:
4
Step-by-step explanation:
circumference = 2πr
or, 20 = 2π r
or, π r = 10
or, r= 10/π
72 ° = 2π/5
length of arc = r∅ = 10/π × 2π/5
= 4
The equation for a trapezoid is a+b/2*h. In this case, we have 3.2+8/2.
So 5.6=22.4/h. The height is 4 feet.
