Answer:
25.12 inch³
Step-by-step explanation:
The volume formula for a cone is 1/3 πr²h
sub in the numbers to get the volume
1/3 x 4 x 3.14 x 6 = 25.12
№1. Given: r=8 ft, π≈3.14
C=2×π×r=2×3.14×8=50.24=50.2 ft
A=π×r²=3.14×64=200.96=201 ft²
Answer: 50.2 ft; 201 ft²
№2. Given: D=11 cm, π≈3.14
d=2r or r=2/d, so if d is 11 cm, then r is 11÷2=5.5 cm
C=2×π×r=πD=3.14×11=34.54=34.5 cm
A=π×r²=3.14×(5.5)²=94.985=95 cm²
Answer: 34.5 cm; 95 cm²
To find the inverse function, interchange the variables and solve for y.
f^-1(n) = 1/2 + n/3
To determine how many times larger the peach got, you will divide the new diameter by the original diameter length.
188869/98 = 1927.2
The new diameter is approximately 1927 times longer.
To convert this to scientific notation, move the decimal point from the end (on the right) to between the 1 and the 9 to get 1.927.
Then count the number of decimal places you moved to get there, because this represents how many groups of 10 you adjusted your place value by and then becomes your exponent in scientific notation.
1.927 x 10^3 times is the answer in scientific notation.
What’s the question?
If it’s area then the formula is pi r^2
If it’s the circumference then the 2pi r or pi d
