Answer: See explanation
Step-by-step explanation:
A pizza is in the shape of a circle.
Since the perimeter is 10 inches, we have to find the radius. This will be:
2πr = 10
πr = 10/2
πr = 5
3.14r = 5
r = 5/3.14
r = 1.5924
Area = πr²
= 3.14 × 1.5924²
= 7.96 inches
= 8 inches approximately
The answer would be 852.17. The number is the hundredths place is 7.
Answer:
R X 4

Answer:
24s^2, 54s^2, 96s^2
Step-by-step explanation:
Let s represent the initial side length of the cube. Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).
a) Now suppose we double the side length. The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),
b) tripled: A = 6(3s)^2 = 54x^2
c) quadrupled? A = 6(4s)^2 = 96s^2
