let's recall that, arc's angle measures come from the central angle they're in.

if this intercepted arc is 80°, and is intercepted by an angle stemming from the center, namely a central angle, then the angle is also 80°. Check the picture below.

Brett warmed up for his basketball game by running around the court 3 times . If the court is 84 feet by 50 feet, how many feet

lana [24]

Answer:

804 feet

Step-by-step explanation:

Given: Dimension of a basketball court is 84 feet by 50 feet.

Considering the shape of basketball court is in rectangle shape.

∴ Finding the perimeter of rectangle to know total number of feet in one round.

Perimeter of rectangle= $2(l+w)$

where, l= length

w= width

∴ Perimeter of rectangular court= $2(84\ feet + 50\ feet)$

⇒ Perimeter of rectangular court= $2(134\ feet)$

Opening parenthesis

⇒ Perimeter of rectangular court= $2\times 134\ feet= 268\ feet$

Hence, Brett run 268 feet in one round of warm up.

As given, Brett ran around the court 3 times.

∴ Total number of feet= $268\ feet\times 3= 804\ feet$

Hence, Brett jog for 804 feet.

Katrina wants to build a fence around her Square Garden the garden has an area of 121 square feet How much Fencing will Katrina

Sindrei [870]

Answer:

The perimeter of the fencing is 44 feet (Option D)

Step-by-step explanation:

Area and Perimeter

A square shape of side length (a) has an area given by:

$A = a^2$

And its perimeter is calculated as:

P = 4a

The area of Katrina's square garden is given as A=121 square feet. We need to calculate the side length by solving for a:

$a=\sqrt{121}$

a = 11 feet

Once we know the value of a, then we calculate the perimeter:

P = 4*11 = 44

The perimeter of the fencing is 44 feet (Option D)
