Answer:

541.17ft^2

Step-by-step explanation:

the total area of the garden is the sum of area of rectangle and half of area of circle

area of rectangle=(l)(h)=(23)(18)=414

area of semicircle=1/2pir^2

since r is half of h=1/2(18)=9

area of semicircle=1/2pi(9)^2=127.17

total area of garden=414+127.17=541.17 ft^2

The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Please show all work.

A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)

Answers


You meed to subtract and divide

Answer:

the circumference is 5, since the diameter is half, so you have to double 2.5 to get 5.    2.5 + 2.5 = 5

if the tire rotates 1 time and gains 5 feet, we have to divide 5 from 5,280. So...

5,280 ÷ 5 = 1056

it rotates 1056 times to get to 1 mile!

What are the circumference and diameter of a circle?

The circumference of a circle is the distance around the circle which is 2πr.

The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.

Given, A circle has a circumference of 50.24 feet.

We know the circumference of a circle is 2πr.

Therefore, 2πr = 50.24.

πr = 50.24/2.

πr = 25.12.

r = 25.12/3.14.

r = 8 feet.

We also know the area of a circle is πr².

= π(8)² square feet.

= 200.96 square feet.

Student 3 determines the area correctly.
