Answer:
True
Step-by-step explanation:
![V=lwh\\\\lwh=V\\\\\frac{lwh}{lh}=\frac{V}{lh}\\\\ \boxed{w=\frac{V}{lh}}; l\neq 0](https://tex.z-dn.net/?f=V%3Dlwh%5C%5C%5C%5Clwh%3DV%5C%5C%5C%5C%5Cfrac%7Blwh%7D%7Blh%7D%3D%5Cfrac%7BV%7D%7Blh%7D%5C%5C%5C%5C%20%20%5Cboxed%7Bw%3D%5Cfrac%7BV%7D%7Blh%7D%7D%3B%20%20l%5Cneq%20%200)
The answer should be true.
To evaluate the radius of the cone we proceed as follows:
V=1/3 πr²h
plugging in the values, v=88π, h=8 ft
step 1
88π1/3πr²(8)
step 2
88π=8/3πr²
step 3
divide both sides by π
88=8/3r²
multiply both sides by 3/(8)
88(3/8)=r²
step 4
simplify
33=r²
step 5
get the square root
r=√33
Thus the mistake that Fatima made was:
<span> In step 3, Fatima did not multiply 88 by the reciprocal of 8/3 </span>
Answer:
3077.2
Step-by-step explanation:
A circle's mass is found by
Pie times R^2
7^2 is 49, times 3.14 is 153.86
then you Multiply 153.86 by 20 which gives you 3077.2
In ΔABC,
tanA = a/b
∴ a = b×tanA = 12×1/√3 = 6.928 ~ 6.93 m
0.48=48/100=12/25~~~12/25>11/25 True✔ ~~~~Have a nice day!!! ★★
