Find the radius of a circle having area 616cm square.​
OLEGan [10]

Answer:

\boxed{\sf Radius \ of \ circle = 14 \ cm}

Given:

Area of circle = 616 cm²

To Find:

Radius of circle

Step-by-step explanation:

\sf \implies Area \ of \ circle = \pi r^{2}  \\  \\  \sf \implies 616 =  \frac{22}{7}  \times  {r}^{2}  \\  \\  \sf \implies 616 \times  \frac{7}{22}  =  {r}^{2}  \\  \\  \sf \implies 28 \times  \cancel{22} \times  \frac{7} { \cancel{22}}  =  {r}^{2}  \\  \\  \sf \implies 28 \times 7 =  {r}^{2}  \\  \\  \sf \implies 196 =  {r}^{2}  \\  \\  \sf \implies  {r}^{2}  = 196 \\  \\  \sf \implies r =  \sqrt{196}  \\  \\  \sf \implies r =  \sqrt{ {14}^{2} }  \\  \\  \sf \implies r = 14 \: cm

In the given figure, the area of △ADE is 16 units. What is the area of △ABC?
Sunny_sXe [5.5K]

Answer:

(i) Triangle ABC and triangle ADE are similar triangles. Hence, their ratios will be same.

Ratio of DE to BC is 4:6 => 2:3

To find area, we need to raise the ratio of length to power 2

(2/3)² = 16/x

4/9 = 16/x

x = (16*9)/4

x = 36cm²

Therefore, area of triangle ABC is 36cm²

(ii) Ratio of DE to BC is 4:8 => 1:2

(1/2)² = 25/x

1/4 = 25/x

x = 25*4

x = 100cm²

Therefore, area of triangle ABC is 100cm²

I'm not sure about the third question, sorry

Maddie converts z = 8(cos(300°) + isin(300°)) into rectangular form z = a + bi and determines that a = 4 and b = 4 StartRoot 3 E
Anastaziya [24]

Answer:

Option C) The value of a is correct, but the value of b is incorrect.

Step-by-step explanation:

z = 8(cos(300°) + isin(300°))

z = 8cos(300°) + 8isin(300°)

z = 4 + i(-4\sqrt{3})\\z=4-i(4\sqrt{3} )\\

So we can see that a = 4 which is correct but b = -4\sqrt{3} and b in the question says it is b 4\sqrt{3} so its incorrect so Option C is your answer.
