The temperature in degrees Celsius can be determined using the expression 5 9 (F – 32) where F is the temperature in degrees Fah
Norma-Jean [14]

Answer:

The temperature on Celsius scale for 86 ºF is 30 ºC.

Step-by-step explanation:

Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:

T_{C} = \frac{5}{9}\cdot (T_{F}-32) (1)

Where:

T_{F} - Temperature, measured in degrees Fahrenheit.

T_{C} - Temperature, measured in degrees Celsius.

If we know that T_{F} = 86\,^{\circ}F, then its equivalent temperature on Celsius scale is:

T_{C} = \frac{5}{9}\cdot (86-32)

T_{C} = 30\,^{\circ}C

The temperature on Celsius scale for 86 ºF is 30 ºC.

Answer:

Area:  200.96 cm

Circumference:  50.24 cm

Explanation: I recently just learned this.  The area of a circle is Pi times radius squared which makes.  3.14 x 8^2 = 3.14 x 64 = 200.96.  SInce none of the original measurements are squared it will be    200.96 cm

The circumference of a circle is diameter times pi which makes  3.14 x (8 x 2) = 3.14 x 16 = 50.24.  Since none of the original measurements are squared it will be 50.24 cm

I hope this helps!  pls mark brainliest if it helps!
