b= 14 because the formula to find a triangles area is 0.5bh. So, you take 147 and divide it by 21 then multiply the answer of that (which is 7) by 2 because the reciprocal of 0.5 is 2.
Because 8.6 is technically 8.600000...
So, you can do...
8.6000
-0.0047
_______
8.553. Hope this answer helps!!!
Answer:
The area of the circle is 314mm²
Step-by-step explanation:
To solve this problem we have to use the formula for calculating the area of a circle
a = area
π = 3.14
r = radius
d = diameter
r = d/2
r = 20mm / 2
r = 10mm
a = π * r²
we replace the known values
a = 3.14 * (10mm)²
a = 3.14 * 100mm²
a = 314mm²
The area of the circle is 314mm²
10 feet is greater than 3 yards
Answer:
here!
Step-by-step explanation:
"In decimal form, the value of pi is approximately 3.14."
