Answer:
AWWWWW :( SOOOOO SAD!!!
Step-by-step explanation:
BUT TRU UNFORINATLEY
Speed = Distance / Time
Distance = 287 miles , Time = 3 hours and 30 minutes = 3.5 hours
Speed = 287 miles / 3.5 hours
= 82 miles/hour
When you write the equation of a circle in the form
Then the center of the circle has coordinates and the radius is
So, in your case, the center of the circle is
Hi there!
The total surface area (tsa) of a cone can be calculated with this formula :
TSA = ( × r × slant height) + × r²
The "r" stands for "radius". The radius is equal to half the diameter, so in order to be able to use the formula, you'll need to divide the diameter by 2 to find the radius :
5 ÷ 2 = 2.5 = radius
Since the slang height is in meters, you'll need to transform it into centimeters in order to have both values in centimeters. To do so you'll need to use the cross product method :
1 m = 100 cm
4 m = x cm
(100 × 4) ÷ 1 = x cm
400 ÷ 1 = x cm
400 = x cm → The slant height is 400cm.
Now replace all the information in the formula and calculate everything :
TSA = ( × 2.5 × 400) + ( × 2.5²)
TSA = ( × 1,000) + ( × 6.25)
TSA ≅ 3,141.59 + 19.63
TSA ≅ 3,161.22 cm²
There you go! I really hope this helped, if there's anything just let me know! :)
Let A be Area, s sides
A= s²
(400)1/4 = area of the smaller square.
100=s²
10²=s²
s= 10, so the smaller side is 10 inches.
