To calculate the are of the sides of a cylinder, you take the circumference of the base, or circle, and multiply it times the height. To calculate the circumference of a circle we use the formula 2*pi*r, or 15pi. We multiply this times 20 to get 300pi cm. If you are using 3.14 for pi, this is 942, or if you are using actual pi, around 942.4777.
In this question, the triangles are congruence which means that the two triangles will have same side and angle. The corresponding part can be seen from how the triangle is written. In this case, the triangle seems to be reflected with vertical lines. Using the picture it would be:
PQ= TS
QR=SR
RP=RT
Since your written answer is not same with the picture, then the written answer version would be:
PA=HE
AR=ER
RP=RH
The answer is 66 kilometers.
Start with the given expression: 12g where 'g' standts for the liters of gasoline.
Input your data and solve: 12 * 5.5 = 66
Answer:
1
Step-by-step explanation:
Note sin²x + cos²x = 1 is an identity and is true for any value of x, thus
sin²2019° + cos²2019² = 1
