Answer:

50.265 ft^{2}

Step-by-step explanation:

The formula of the area of a circle is \pi r^{2} and the diameter is double the amount as the radius, so the radius would be 4 feet. 4 squared is 16. Multiply that by pi to get your answer, 50.265ft^{2}.

Dmitry [639]

Answer:

3 Blue Umbrellas

Step-by-step explanation:

Given

B \to Blue

Y \to Yellow

R \to Red

From the question, we have:

Y + R = 6 ---- i.e. 6 are not blue

B + R = 6 ---- i.e. 6 are not yellow

B + Y = 6 ---- i.e. 6 are not red

Required

The number of blue umbrellas

Make B the subject in: B + Y = 6

B = 6 - Y

Substitute: B = 6 - Y in B + R = 6

6 - Y + R = 6

Collect like terms

R - Y = 6 - 6

R - Y = 0

Rewrite:

R = Y

Substitute R = Y in Y + R = 6

Y + Y = 6

2Y = 6

Divide both sides by 2

Y=3

Recall that: B = 6 - Y

B = 6 - 3

B = 3
