Answer:
The surface area is 3140 feet².
What is Surface Area?
Surface area is the amount of space covering the outside of a three-dimensional shape.
Given that:
Diameter = 20 feet
radius = 20 ÷ 2 = 10 feet
Now, Surface area will be,
=2πr²+ 2πrh
= 2 × 3.14 × (10)² + 2 × 3.14 × 10 × 40
= 6.28 × 100 + 6.28 × 400
= 628 + 25.12 × 100
= 628+ 2512
= 3140 feet²
hence, the surface area is 3140 feet².

Step-by-step explanation:
6*[4-(42-63)]=
6*[4-(-21)]=
6*[4+21]=
6*25=150.
6*[4-9÷3]=
6*[4-27]=
6*(-23)=-138.
6*[4-3]=
6*1=6.
Answer:
8 units, 4 tenths and 6 hundredths
Step-by-step explanation:
The decimal number 8.46 can be expressed as following
The number at unit place is 8
The number at tenth place is 4
The number at hundredth place is 6
The rate of change is the slope. The slope is the number in front of the x
Function 1 rate of change is -1/2
Function 2 rate of change is -3/4
The greater rate of change would be the steepest slope.
Function 2 has the greater rate of change
