Mathematics

Ganezh [65]3 years ago

Answer: 10 units.

Step-by-step explanation:

The equation of the circle in Center-radius form is:

(x - h)^2 + (y - k)^2 = r^2

Where the center is (h,k) and "r" is the radius.

The equation of the circle given is:

x ^2 + y^2 = 100

You can observe that is written in Center-radius form.

Then, you can identify that:

r^2=100

Knowing this, you need to solve for "r" to find the lenght of the radius.

This is:

r=\sqrt{100}\\\\r=10

Therefore, the lenght of the radius is 10 units.

Elena is 56 inches tall. What is her height in centimeters? (Note: 100 inches = 254 centimeters) What is her height in meters?
LUCKY_DIMON [66]

Answer:

142.24cm

Step-by-step explanation:

If 100 inches = 254cm then if you do 254/100 you will get how many cm are in an inch. 254/100 = 2.54

This means there are 2.54 cm in an inch. Multiply 2.54cm by 56 inches and you get how many cm are in 56 inches which is 142.24cm. This means Elena is 142.24 cm tall.

A Triangle has an area of 36cm^2. The base and height are scaled by a factor of 5. What is the area of the resulting triangle?
Finger [1]

Answer:

Area of resulting triangle  will be 900 cm^2.

Step-by-step explanation:

When sides of  any polygon if scaled by a factor of k

then area is scaled by k^2

According to the above statement

therefore  here in the question since area of original triangle was 36cm^2

and both  base and height are scaled by a factor of 5.

therefore area of scaled triangle will be 5^2 times of the original

that is 25 x 36 which gives 900 cm^2

So area of resulting triangle will be 900 cm^2
