If the circumference of the shield is 100.48inches, nits radius is 16 inches and the area of the front of the shield is about 803.84 square inches.
proof

circumference = 2x r x Pi implies r =<span>circumference / 2Pi=100.48/2x3.14=16
area = Pi x r²=3.14 x 16²=804.84

Answer:

The radius of shield is 16 inches and the area of front of the shield is 803.84 inches^2

Step-by-step explanation:

Circumference of circle = 2\pi r

Circumference of the shield is 100.48 inches

⇒2 \pi r = 100.48

⇒2\times 3.14 \times r = 100.48

⇒6.28\times r = 100.48

⇒r = \frac{100.48}{6.28}

⇒r = 16

Thus the radius of shield is 16 inches

Area of shield = \pi r^2

                       = 3.14 \times (16)^2

                       = 803.84 inches^2

Hence the radius of shield is 16 inches and the area of front of the shield is 803.84 inches^2

A group of 18 people ordered soup and sandwiches for lunch. Each person in the group either ordered one soup or one sandwich . T
kkurt [141]
Let's say a = number of ordered soups, b = number of ordered sandwiches.

Then 4.5a + 7.75b = 113.50, and a and b are integers between 0 and 18 inclusive.

How do we tackle this? If all ordered soup, the cost would be $81, so we'll have at least 4 sandwiches. If all ordered sandwich, the cost would be $139.5, so at most 15 sandwiches were ordered. You also know an even number of sandwiches was ordered, to let the price end at 50 cent.

If you brute-force from 4,6,8,10,12 to 14 sandwiches, you find the answer at 10 sandwiches and 8 soups.

10*7.75 + 8*4.50 = 113.50

A hat is on sale for h dollars. The regular price is 7 times as much. Charlie has enough money to buy two hats at the regular pr
Nostrana [21]

Answer:

Charlie can buy 14 hats at the sale price

Step-by-step explanation:

Let

h ----> the sale price of the hat

x ---> the regular price of the hat

we know that

x=7h ----> equation A

so

Two hats at the regular price  is equal to multiply 2 by x

Multiply by 2 equation A both sides

2x=(7h)*2

2x=14h

2 hats at the regular price cost the same that 14 hats at the sale price

therefore

Charlie can buy 14 hats at the sale price

Two sides of an isosceles triangle have lengths of 3 and 10. Find the length of the third side.
lora16 [44]

Answer:

The third side must be 10:  {3, 10, 10}; {10, 3, 3} is not possible.

Step-by-step explanation:

Everything depends on our understanding of "isosceles."

This term indicates that two sides of a given triangle are equal.

If two sides of an isosceles triangle have lengths of 3 and 10, then:

Either 1)  Two sides have length 10 and the third side has length 3.  This is certainly possible

or

2)  sides have length 3 and the third side has length 10.  This is NOT possible, since 3 + 3 adds up to 6, which is less than 10.
