Answer:
She put decimal in the wrong place.
Step-by-step explanation:
Consider the provided sentence.
9 × 0.989 = 89.01
Estimate the number 0.989 to nearest natural number.
The estimation of the number 0.989 to the nearest natural number is 1.
Now multiply 9 with 1.
9 × 1 = 9
Hence, the product should be less than 9.
Since the product of 9 and 0.989 is 89.01 which is greater than 9.
Thus, we can concluded that Jen's answer is wrong.
She put decimal in the wrong place, the required product must be 8.901
Here, you can observe that the number 8.901 is less than 9 and estimation of the number to the nearest natural number is 9.
The length of an arc is given by (θ/360)2πr, where θ is the angle subtended by the arc at the center and r is the radius.
The angle θ in this case is 270°, while the radius is 7 feet, diameter is 14 feet
Thus the length of the of the cable will be;
=(270/360)× 22/7×14
= 0.75 × 44
= 33 feet
It is 75.36 because the total volume is 301.59 and 25% of the cone remains so 25% of 301.59 is 75.36
Answer:803.84
Step-by-step explanation:
3.14 x (16^2) = 803.84.
16^2 is 256 so multiply that by 3.14
