Answer:
25πm²
Step-by-step explanation:
Circumference of the circular sculpture = πd
d is the diameter
Given
Circumference = 10π metres
Substitute into the formula
10π = πd
10 = d
d = 10m
Area of the sculpture = πd²/4
area of the sculpture = π(10)²/4
area of the sculpture = 100π/4
area of the sculpture = 25π m²
Hence the measurement closest to the area of the sculpture in square meters is 25πm²
A - Area
V - Volume
A = 4piR^2
V = 1.33piR^3
With the info given, 289 = 4piR^2, making R = 4.8
Plug this into the volume formula, and you'll get 1.33*pi*(4.8^3), which equates to 463.3 cubic centimeters.
Answer:
48x + 216 square inches.
Step-by-step explanation:
Area is length X width.
Area is (4x + 18)(12).
in 4x + 18, 18 comes from adding the three 6 in.
We have no values for "x", so expand the equation and simplify.
(4x + 18)(12)
= 48x + 216
Step-by-step explanation:
1 + 7 = 8
2 + 6 = 8
3 + 5 = 8
+ 
= 8
+ + + = 8
+ = 8
