Answer:
- 615.8 square feet
- 9 truckloads
Step-by-step explanation:
The area of the circular ring is given by the formula ...
A = πr²
where r is the radius, or half the diameter.
A = π(14 ft)² = 196π ft² ≈ 615.752 ft²
The area of the training area is about 615.8 square feet.
__
The number of truckloads of dirt required for coverage will be ...
(615.8 ft²)/(75 ft²/truckload) ≈ 8.21 truckloads
Since the dirt comes only in whole truckloads, Hilary needs 9 truckloads.
Hyp^2 = a^2 + b^2
sqrt (hyp) = 2
hyp = 4
hyp^2 = 16 then from above a^2 + b^2 = 16
Answer:
14.24 foot far is the mirror from the base of the statue.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
As per the statement:
See the diagram as shown below:
Height of a boy = 5.9 foot tall
Height of a statue = 12 foot.
Distance of a boy from the mirror = 7 feet.
Let x be the distance of the mirror from the base of the statue.
then by definition of proportion we have;

Substitute the given values we have;

By cross multiply we have;

Divide both sides by 5.9 we have;
x = 14.24 ft
Therefore, 14.24 foot far is the mirror from the base of the statue.
