Big Ben (the clocktower) in London has a circumference of 72.22 feet and an area of 415.27 feet^2. What is the diameter AND radi

Mashutka [201]

Answer:

Diameter = 23 Radius = 11.5

Step-by-step explanation:

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

72.22 ÷ 3.24 = 23

diameter = 23

Divide the diameter by 2.

23 ÷ 2 = 11.5

There you go, you found the circle's radius

An Isosceles Triunde

Amanda [17]

Answer:

base = $x^4 - 3x^3+11x-4$

Step-by-step explanation:

An isosceles triangle has 2 sides of equal length (a) and base (b)

⇒ perimeter of an isosceles = 2a + b

Given:

$\textsf{leg (a)}=3x^4 - 6x-1$

$\textsf{perimeter}=7x^4 - 3x^3-x-6$

$\implies \textsf{perimeter}=2a+b$

$\implies 7x^4 - 3x^3-x-6=2(3x^4 - 6x-1)+b$

$\implies 7x^4 - 3x^3-x-6=6x^4 - 12x-2+b$

$\implies x^4 - 3x^3+11x-4=b$

Therefore, base = $x^4 - 3x^3+11x-4$

RUDIKE [14]

She can make 11 costumes

I found this by dividing the two numbers and when dividing them i got 11,1/4 but you can't have 1/4 of a costume so it would only be 11

Hope this helps
