Here you would want to use the sine function, since it’s making a triangle with the ground, and length of the string, the height to the kite. This can be found by 65sin(70°) which is ≈ 61.08 meters

Volume of cylinder is 3 times of volume of cone having same base diameter and same height.

<u>Solution:</u>

Given that  

A cylinder and A cone have the same diameter = 10 inches and same height = 12 inches

Need to find the relationship between volume of cylinder and cone.

Let’s calculate volume of each object separately first.

<em><u>Calculation of volume of cylinder :</u></em>

Formula of volume of cylinder is given as:

V_{c y}=\pi r^{2} h

Where π=3.14

\text { radius } r=\frac{\text {diameter}}{2}=\frac{10}{2}=5 \text { inches }

height h = 12 inches  

On substituting given values in formula of cylinder we get

\begin{array}{l}{V_{c y}=3.14 \times 5^{2} \times 12=942 \text { cubic inches }} \\\\ {\text { Volume of cylinder }=V_{c y}=942 \text { cubic inches }}\end{array}

<em><u>Calculation of volume of cone:</u></em>

Formula of volume of cone is given as:

V_{c o}=\frac{\pi r^{2} h}{3}

Here π=3.14

\begin{array}{l}{\text { radius } r=\frac{\text { diameter }}{2}=\frac{10}{2}=5 \text { inches }} \\\\ {\text { height } \mathrm{h}=12 \text { inches }}\end{array}

On substituting given values in formula of cone we get

V_{c o}=\frac{3.14 \times 5^{2} \times 12}{3}=314 \text { cubic inches }

\text { Volume of cone }=V_{c o}=314 \text { cubic inches }

On comparing the two volumes we get  

V c y: V c o=942: 314=3: 1

Hence can conclude that Volume of cylinder is 3 times of volume of cone having same base diameter and same height.

Fon baked a cake and ate 1/8 of it she shared the remaining cake equally to her 4 friends whag Frection of the whole cake did ea
jok3333 [9.3K]

Answer:

Each of her friends ate 7/32 of the cake.

Step-by-step explanation:

Given that Fon baked a cake and ate 1/8 of it, and then she shared the remaining cake equally to her 4 friends, to determine what fraction of the whole cake did each of her friends received, the following calculation must be performed:

(8 - 1/8) / 4 = X

(7/8) / 4 = X

(28/32) / 4 = X

7/32 = X

Thus, each of her friends ate 7/32 of the cake.
