"Around the garden"= circumference
Find diameter from circumference formula
Circumference= πd
19= (3.14)d
divide both sides by 3.14
6.04788= d
Find radius
d÷2= 3.0239
Insert r= 3.0239 into Area formula
Area= πr^2
A= π(3.0239)^2
A= (3.14)(3.0239)^2
A= 28.71 square feet
ANSWER: 28.71 square feet is the area of the new garden
Hope this helps! :)
Answer:
one ton :)
Step-by-step explanation:
You just multiply 1.5x10^3 by 4.3x10^2. 1.5x10^3 is equal to 1500 (move the decimal to the right as many spaces as the exponent gives) and 4.3x10^2 is equal to 430. 1500*430=645000. To get that back down to scientific notation, we would have to move the decimal back to between the 6 and 4 to get 6.45 (Zeros aren't included in scientific notation) We moved the decimal to the left five spaces do the exponent is 10^5. We are left with 6.45x10^5
answer B. 108°
because 30% of 360 = 108°
