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! :)
Answer:
f(x) = x - 3
Step-by-step explanation:
note that y = f(x) , then
x - y = 3 ( add y to both sides )
x = 3 + y ( subtract 3 from both sides )
x - 3 = y , that is
f(x) = x - 3
Answer:
6 x25/4=75/2
150/4=75/2
simplify 150/4
75/2=75/2

Answer:
The dimensions of triangle are 66 ft, 33 ft and 47 ft
Step-by-step explanation:
Let
x -----> the length of one side
y -----> the length of the shortest side
z -----> the length of the third side
we know that
The perimeter of triangle is


so
-----> equation A
-----> equation B
----> equation C
Substitute equation B and C in equation A and solve for y





<em>Find the value of x</em>
<em>Find the value of z</em>
therefore
The dimensions of triangle are 66 ft, 33 ft and 47 ft
0.35 is the answer because
0.35 x 1 is 0.35
